5. Torque and Rotational Dynamics

Connecting Linear And Rotational Motion — Quiz

Test your understanding of connecting linear and rotational motion with 5 practice questions.

Practice Questions

Question 1

A point on the rim of a spinning wheel is $0.50\,\text{m}$ from the axis of rotation. If the wheel has angular speed $4\,\text{rad/s}$, what is the point's linear speed?

Question 2

An object moves farther from the axis of rotation while keeping the same angular speed. What happens to its linear speed?

Question 3

What is the angular displacement of a wheel that turns through one full revolution?

Question 4

A point on a rotating disk is $0.20\,\text{m}$ from the center. If the disk's angular acceleration is $6\,\text{rad/s}^2$, what is the point's tangential acceleration?

Question 5

Which statement best describes centripetal acceleration for a point moving in a circle at constant speed?
