RDO-01: Rotational Motion – Worksheet

Maximum Score: 13

Part A

1. [2] In uniform circular motion, what is the direction of the linear velocity at each instant? Draw a picture if this helps you explain. Describe how your answer is evident in the video.

2. [2] What is the direction of the centripetal force required for uniform circular motion? Draw a picture if this helps you explain. Describe how your answer is evident in the video.

Part B

3. [2] Attach a graph of ac vs ω2 that is properly plotted, analyzed and labelled. The data should be reasonable and there should be at least 8 data points. If you do not have at least 8 useful data points, explain how you tried to modify your experiment to collect more data and why you think you were unable to collect the required minimum of 8 data points.

4. [1] What did you look for when ensuring your data points made sense? If you excluded any data points, what made you remove those points? What could explain this outlier data?

5. [1] Which model equation did you choose to fit your data? Why? 6. [1] Write out your fit equation for ac vs ω2. 7. [1] Does your experimental result agree with the expected relationship between centripetal

acceleration and angular velocity? Justify your response. 8. [1] What is your value of r? 9. [2] What does this value of the radius physically represent, and is this result reasonable?
