don't matter here). Please, just make sure that the variables to be measured should be clearly

represented in the figure. Also, you can take screenshots of the demo video (Blackboard > LABS > 02-Back and Forth> Demonstrations).

In summary, use the method that is easiest for you to represent the experimental situation and the variables to be measured.

Part IV A Mass Oscillating at the End of a Spring

Create a figure that describes the experiment. In the figure show clearly the variables to be measured.

Part V Ball Tossed into the Air

Create a figure that describes the experiment. In the figure show clearly the variables to be measured.

Procedure:

Part I Oscillating Pendulum

This section should identify and name all experimental variables and briefly describe how the

independent variables are controlled.

By watching the video of the experiment in (Blackboard > LABS > 02-Back and Forth>

Demonstrations) and using the PROCEDURE section of the laboratory instructions(Blackboard >

LABS >02-Back and Forth>Lab: 02-Back and Forth), make a brief summary of the steps that

were followed to do this part.

Example:

In this part we launch Graphical Analysis……. With the motion detector we measure…..

Data:

Data consists only of those values measured directly from the experimental apparatus. Although to analyze the data (next section) you use all the rows of the tables. In this

section, just copy and paste a few rows of data from the datafile.

Evaluation of Data:

General instructions for this section:

This selection Should include all graphs, analysis of graphs, and post lab calculations.State each

formula, and if necessary, identify the symbols used in the formula. If repetitive calculations are to

be performed, substitute only one set of data into each formula & then construct a table of values

for all additional calculated values. Be certain that your finals calculated values are expressed in

the correct number of significant figures. DO NOT SHOW YOUR ARITHMETIC

CALCULATIONS.

Specifically, in this laboratory we will not have to use any formula.

Part I: Oscillating Pendulum

Predicted graphs. Graphs from data (datafile)

Sketches: Vernier: Graphs

Example:

My predicted or sketched graphs were very similar to the graphs recorded by the Vernier Graphical Application and the Sensor. This is because I previously knew that a Position Vs.

Time graph ……., while a Velocity Vs. Time graph looks…….

As we can see from the acceleration vs. time graph of the graph below, the acceleration is ….

Here you answered question 2 (Was the acceleration constant or changing? How can you tell?) of

the ANALYSIS section of the laboratory instructions).

The following graph shows the velocity vs time for the pendulum. Here you can see that since the

movement is periodic there are several moments where the graph cuts the time axis (points with zero

speed). In the experimental demonstration, these points correspond to the highest position of the

pendulum ......... In the previous sentence, you answered question 3 (Was there any point in the motion

where the velocity was zero? Explain.)

Then, you answer questions 4 and 5. They are: Was there any point in the motion where the

acceleration was zero? Explain. Where was the pendulum bob when the acceleration was greatest?

I suggest you answer these questions in paragraph format and always

using graphs in the datafile.

Part II: Dynamics Cart on an Incline

The same idea as in the previous part

I suggest you answer these questions in paragraph format and always

using graphs in the datafile.

Analysis of All Parts

Example:

All the Position vs. Time graphs are have in common that…., as well as…

Here you must answer the questions in this section of the lab instructions file.

Conclusion:

In the conclusion you must do the following:

a) State the relationship between the variables identified in the purpose in a clear, concise English

sentence.

b) When a mathematical expression can be derived from graphical analysis, write it, making sure

to include the appropriate units. State the meaning of the slope and discuss the significance of the

y-intercept (when appropriate).

c) Describe any new terms that arise as a result of your evaluation of data.

d) When your results differ from what is expected, provide a plausible explanation

Example:

Each of the graphs of motions we studied displayed back and forth motion, they each had similar

graphs of position vs time in that they oscillated to a certain degree, but their velocity vs time and

acceleration vs time graphs tended to be quite different…… The y-intercept of a position vs. time

graph tells us what our initial position is……..
