Hi Guys! I got some feedback on our experiment from BeachBoard and it says our

experiment looks good and do go ahead and do what our proposal states. Here is the

template for the experiment, I'm the Investigator this week so I will get to writing a more

detailed list of steps for our experiment. Let's get this wrapped up early!

Group #: Title of Experiment Principal Investigator: Director’s Name

Researcher: Investigator’s Name

Analysis: Executive’s Name

Quality Control 1: Skeptic 1’s Name

Quality Control 2: Skeptic 2’s Name

Abstract

We have fulfilled the RFP by filming the motion of (…..) during (….). We have measured (….) from the motion, and willconclude that (….question…) has the following answer: (your answer).

(/CLS/2019/av/profile/192031/013766309)

Background

Project director is responsible for this section. The RFP is asking about some big area of

physics. The Director has to write a paragraph about how this question relates to the rest of

the course … this is the “why are we doing this” question.

Procedure

The Investigator is responsible for making a step by step procedure for how to do the

proposed experiment. The procedure must be detailed enough so that a different group

could follow it. The Investigator is responsible for collectingdata including the filming of the

process, the calibration of distances and masse. The quality control people (Skeptics) check

that this has been done honestly. The data must be included in the appendix.

Result

The Executive analyzes the data and writes a paragraph, and includes a graph answering the

overall RFP “question”.

Conclusion

The skeptics write this paragraph, giving a frank assessment of the quality of the

experiment, and how convincing the results are.

Appendix

The raw data (in the form of a table) containing the raw data.

Analysis: Jassim

Quality Control: Everyone

I will start working on my list of procedures and will film our experiment tomorrow or

Wednesday at the latest. Andrew, can you write up the background and post it here? Then

I will post my video and findings and then Jassim can write up the analysis. Then we can all

look it over and I think we should try to turn in in by Friday, what do you guys think?

Here is the procedure I came up with, let me know what you guys think! I left certain places

blank because I don't have a ball yet and still need to measure its mass.

1. Measure the mass of the ball in Kg and calculate the expected change in momentum:

mass of ball: X Kg

weight: X Kg*9.8m/s^2

(http://latex.codecogs.com/gif.latex?Pfinal%3DPinitial+%5Cbigtriangleup%20t*w)

This image has been resized to fit in the page. Click to enlarge.

2. Hold the ball at the top of a wall and place a measuring tape next to it as a reference.

Record the total distance the ball will drop (in cm, not inches).

3. Film the ball falling until it hits the floor.

4. Upload the video to Tracker and select the correct scale (refer to meauring tape distance

you recorded).

5. Go through the video in Tracker in short time frames and record the data points while

the ball is falling. Track the position of the ball as x,y coordinates for each time interval.

6. Save the data in a table and import it into Excel.

7. In Excel, calculate the velocity and change in momentum for each time interval. Also

make note of the averages so you can compare it with the expected values we calculated in

Step 1.

# (/CLS/2019/av/profile/192031/013766309)

8. Compare the results to the expected values calculated, in theory they should be equal to

each other. If not, analyze why the data might have discrepencies.

I will get a ball and film tonight and upload the video to Tracker and will post the data either

tonight or tomorrow. How are you guys doing on your parts?

Here is the Background:

Learning about the Momentum Principle is so important because without it we would not

be able to accurately predict the behavior of certain objects. The Momentum Principle (also

known as Newton’s Second Law) is something that occurs around us every day even though

we may not realize it. Scientists need it to understand the world around us and without this

basic knowledge there may not have been many other important discoveries in the field of

science. As physics students we need to grasp this knowledge early on so that we can form a

strong base from which we can build upon what we have learned.

The Momentum Principle itself states that the change in momentum of a system is equal to

the net force acting on the system, multiplied by the duration of the interaction:

image

Force is a vector quantity that is used to measure interactions between two objects. The

net force acting on a system is the vector sum of all the forces that are acting on that system

by all of the objects in the surroundings at that point in time:

image

Delta t is simply the duration of time in which the interaction between the two objects

occurs. To find this duration, simply follow this equation:

# (/CLS/2019/av/profile/192029/aleyba24)

image

The experiment that we are performing in our groups gives us hands-on experience with

the Momentum Principle that will help us see for ourselves how the world of physics works.

Working in groups on this experiment also gives us the opportunity to see what it would be

like to work as a team of scientists/physicists observing the world and looking for answers.

Overall, the importance of the Momentum Principle cannot be overstated. In this class this

concept will be the basis from which many other concepts are presented to us. In a lot of

our homework exercises so far, we have been asked to find the change in momentum, either

directly or indirectly. Without being able to understand and use the Momentum Principle,

this would be very difficult to do.

I included the important parts from your write up of the background as well from the

proposal.

The procedure looks good, once everything is posted and finished I will write up a first draft

of the conclusion.

Oh I forgot to mention that the equations in the above post I made won't show up when I

paste them here. Also, let me know if I should add or remove anything from the

The mass of our tennis ball is 56.69g or 0.05669Kg. I dropped it from a height of 6 feet

which is 1.829m. Here is my data from Tracker and the graph. Let me know if you have

questions or need anything else! Now Jassim can analyze, then Andrew can write the first

draft of the conclusions and then Jassim and I can look it over. Go team go!MP Experiment

Amanda, about the data you loaded, I took a simple analysis. Fx is very small, which is good,

as we expected. But Fy is quite a bit off, as we would expect Fy=mg=0.057*9.8N, which is

about 0.56N, but from your data is about 0.08N. I'm thinking maybe the length calibration is

somewhat off? To make sure, can you upload your video here, include the calibration you

used(yard stick or something). I can then put it on tracker, and do the analysis from there.

4e10-a2d2-d9416ba14908/)

In the video I stretched out a tape measure to 6ft and for the calibration I converted it to

meters so I used 1.829m. Sorry about the confusion, I will look at it again too and let me

know if you find where I went wrong. Thanks!

I loaded the video into tracker, and did some analysis. Looks like I got the same problem

when I include all 15 time intervals. The average force of Fy would be too small. But if we

only use the first 8 time intervals, it's much better as the data are more smooth. I'll write it

up soon.

Yeah I started playing around with it tonight too and saw that 8 seemed to fit the best.

Result

With the video clip of the tennis ball of mass 0.05669kg dropping from the height of

1.829m, we uploaded the video into tracker, and tracked the ball movement with time

interval of 0.042s. We then pasted the data points of x,y versus t into Excel, and did the

calculation for rate of change for momentum Px and Py, which should equal Fx and Fy

according to momentum principle. The steps of calculation are the following:

1. We did

to get Vix and Viy.

2. Then we did

to get the momentum Px and Py

3. Then we did

# (/CLS/2019/av/profile/192032/jalsheeb)

To get Fx and Fy

4. The results of Fx and Fy are plotted in the Excel file with units of Newton.

Discussion of the results

From the graph of Fx and Fy, we see that they are both pretty smooth for the first 8 time

intervals, after which it gets quite jumpy, which seems quite unreliable. So we decided to

drop the last few time intervals and only use the first 8 data points. It turns out for these

points, the average Fx is quite small, about 0.0167N, which fits well with the momentume

principle, as there is no force in the horizonatl direction acting on the ball. For Fy, the

average is about 0.635N, which is quite close to the theoretical value as well. The value we

expect is Fy = mg = 0.057*9.8 = 0.559N, so our experiemental error is about (0.635-

0.559)/0.559 = 13.6%.

In summary, our experiment agrees quite well with the expected theoretical value, given

the crude the nature of the expriment. With an error about 13.6%, our answer is yes to the

RFP question of "Is the change in momentum of a system equal to the net force acting on

the system, multiplied by the duration of the interaction". Possible source of error may be the air resistance force that we ignored, and the lack of precision in tracking the exact location of the tennis ball. For graph of our experimental data, please see the attched file.

Good job! I think you laid it out very nicely, I like how you went step by step trough the

equations we used. Now Andrew can write the conclusions, we can proofread them, then

Andrew can post it on beachboard!

Hi guys, My team 2 actually did not consider Y-vector force because we thought it is

negligible because we were convinced that even if the object did not move to y-axis, the

object would not move signficantly further.

But for you guys, I don't think you guys should calculate x-axis in order to simplify the

calculation.

Hi guys, My team 2 actually did not consider Y-vector force

because we thought it is negligible because we were convinced

that even if the object did not move to y-axis, the object would not

move signficantly further.

But for you guys, I don't think you guys should calculate x-axis in

order to simplify the calculation.

I see what you mean now, actually. I did not think about this before, thank you for the

feedback.

Hi Guys! I got some feedback on our experiment from BeachBoard and it says our

experiment looks good and do go ahead and do what our proposal states. Here is the

template for the experiment, I'm the Investigator this week so I will get to writing a more

detailed list of steps for our experiment. Let's get this wrapped up early!

Group #: Title of Experiment Principal Investigator: Director’s Name

Researcher: Investigator’s Name

Analysis: Executive’s Name

Quality Control 1: Skeptic 1’s Name

Quality Control 2: Skeptic 2’s Name

Abstract

We have fulfilled the RFP by filming the motion of (…..) during (….). We have measured (….) from the motion, and willconclude that (….question…) has the following answer: (your answer).

(/CLS/2019/av/profile/192031/013766309)

Background

Project director is responsible for this section. The RFP is asking about some big area of

physics. The Director has to write a paragraph about how this question relates to the rest of

the course … this is the “why are we doing this” question.

Procedure

The Investigator is responsible for making a step by step procedure for how to do the

proposed experiment. The procedure must be detailed enough so that a different group

could follow it. The Investigator is responsible for collectingdata including the filming of the

process, the calibration of distances and masse. The quality control people (Skeptics) check

that this has been done honestly. The data must be included in the appendix.

Result

The Executive analyzes the data and writes a paragraph, and includes a graph answering the

overall RFP “question”.

Conclusion

The skeptics write this paragraph, giving a frank assessment of the quality of the

experiment, and how convincing the results are.

Appendix

The raw data (in the form of a table) containing the raw data.

Here is the procedure I came up with, let me know what you guys think! I left certain places

blank because I don't have a ball yet and still need to measure its mass.

1. Measure the mass of the ball in Kg and calculate the expected change in momentum:

mass of ball: X Kg

weight: X Kg*9.8m/s^2

(http://latex.codecogs.com/gif.latex?Pfinal%3DPinitial+%5Cbigtriangleup%20t*w)

This image has been resized to fit in the page. Click to enlarge.

2. Hold the ball at the top of a wall and place a measuring tape next to it as a reference.

Record the total distance the ball will drop (in cm, not inches).

3. Film the ball falling until it hits the floor.

4. Upload the video to Tracker and select the correct scale (refer to meauring tape distance

you recorded).

5. Go through the video in Tracker in short time frames and record the data points while

the ball is falling. Track the position of the ball as x,y coordinates for each time interval.

6. Save the data in a table and import it into Excel.

7. In Excel, calculate the velocity and change in momentum for each time interval. Also

make note of the averages so you can compare it with the expected values we calculated in

Step 1.

# (/CLS/2019/av/profile/192031/013766309)

8. Compare the results to the expected values calculated, in theory they should be equal to

each other. If not, analyze why the data might have discrepencies.

I will get a ball and film tonight and upload the video to Tracker and will post the data either

tonight or tomorrow. How are you guys doing on your parts?

Here is the Background:

Learning about the Momentum Principle is so important because without it we would not

be able to accurately predict the behavior of certain objects. The Momentum Principle (also

known as Newton’s Second Law) is something that occurs around us every day even though

we may not realize it. Scientists need it to understand the world around us and without this

basic knowledge there may not have been many other important discoveries in the field of

science. As physics students we need to grasp this knowledge early on so that we can form a

strong base from which we can build upon what we have learned.

The Momentum Principle itself states that the change in momentum of a system is equal to

the net force acting on the system, multiplied by the duration of the interaction:

image

Force is a vector quantity that is used to measure interactions between two objects. The

net force acting on a system is the vector sum of all the forces that are acting on that system

by all of the objects in the surroundings at that point in time:

image

Delta t is simply the duration of time in which the interaction between the two objects

occurs. To find this duration, simply follow this equation:

# (/CLS/2019/av/profile/192029/aleyba24)

image

The experiment that we are performing in our groups gives us hands-on experience with

the Momentum Principle that will help us see for ourselves how the world of physics works.

Working in groups on this experiment also gives us the opportunity to see what it would be

like to work as a team of scientists/physicists observing the world and looking for answers.

Overall, the importance of the Momentum Principle cannot be overstated. In this class this

concept will be the basis from which many other concepts are presented to us. In a lot of

our homework exercises so far, we have been asked to find the change in momentum, either

directly or indirectly. Without being able to understand and use the Momentum Principle,

this would be very difficult to do.

I included the important parts from your write up of the background as well from the

proposal.

Amanda, about the data you loaded, I took a simple analysis. Fx is very small, which is good,

as we expected. But Fy is quite a bit off, as we would expect Fy=mg=0.057*9.8N, which is

about 0.56N, but from your data is about 0.08N. I'm thinking maybe the length calibration is

somewhat off? To make sure, can you upload your video here, include the calibration you

used(yard stick or something). I can then put it on tracker, and do the analysis from there.

In the video I stretched out a tape measure to 6ft and for the calibration I converted it to

meters so I used 1.829m. Sorry about the confusion, I will look at it again too and let me

I loaded the video into tracker, and did some analysis. Looks like I got the same problem

when I include all 15 time intervals. The average force of Fy would be too small. But if we

only use the first 8 time intervals, it's much better as the data are more smooth. I'll write it

up soon.

Result

With the video clip of the tennis ball of mass 0.05669kg dropping from the height of

1.829m, we uploaded the video into tracker, and tracked the ball movement with time

interval of 0.042s. We then pasted the data points of x,y versus t into Excel, and did the

calculation for rate of change for momentum Px and Py, which should equal Fx and Fy

according to momentum principle. The steps of calculation are the following:

1. We did

to get Vix and Viy.

2. Then we did

to get the momentum Px and Py

3. Then we did

# (/CLS/2019/av/profile/192032/jalsheeb)

To get Fx and Fy

4. The results of Fx and Fy are plotted in the Excel file with units of Newton.

Discussion of the results

From the graph of Fx and Fy, we see that they are both pretty smooth for the first 8 time

intervals, after which it gets quite jumpy, which seems quite unreliable. So we decided to

drop the last few time intervals and only use the first 8 data points. It turns out for these

points, the average Fx is quite small, about 0.0167N, which fits well with the momentume

principle, as there is no force in the horizonatl direction acting on the ball. For Fy, the

average is about 0.635N, which is quite close to the theoretical value as well. The value we

expect is Fy = mg = 0.057*9.8 = 0.559N, so our experiemental error is about (0.635-

0.559)/0.559 = 13.6%.

In summary, our experiment agrees quite well with the expected theoretical value, given

the crude the nature of the expriment. With an error about 13.6%, our answer is yes to the

RFP question of "Is the change in momentum of a system equal to the net force acting on

the system, multiplied by the duration of the interaction". Possible source of error may be the air resistance force that we ignored, and the lack of precision in tracking the exact location of the tennis ball. For graph of our experimental data, please see the attched file.

Hi guys, My team 2 actually did not consider Y-vector force because we thought it is

negligible because we were convinced that even if the object did not move to y-axis, the

object would not move signficantly further.

But for you guys, I don't think you guys should calculate x-axis in order to simplify the

calculation.

Hi guys, My team 2 actually did not consider Y-vector force

because we thought it is negligible because we were convinced

that even if the object did not move to y-axis, the object would not

move signficantly further.

But for you guys, I don't think you guys should calculate x-axis in

order to simplify the calculation.

I see what you mean now, actually. I did not think about this before, thank you for the

feedback.
