Question 1.
Define angular velocity.
Show hintHide hint
Think about how fast something spins around.
Question 2.
What is the unit for angular acceleration?
Show hintHide hint
Consider how you express acceleration in linear motion.
3Question 3.
What is the primary formula for calculating angular velocity?
- \\(\\omega = \\frac{\\theta}{t}\\)
- \\(\\omega = \\frac{t}{\\theta}\\)
- \\(\\omega = \\theta \\cdot t\\)
Show hintHide hint
Consider how angular displacement relates to time.
4Question 4.
True or False: Angular acceleration can be zero if the object is in uniform motion.
- True
- False
Show hintHide hint
Think about objects that move at a constant rate.
Question 5.
A Ferris wheel has an angular velocity of 2 rad/s and an angular acceleration of 0.5 rad/s². How much time will it take to reach an angular velocity of 5 rad/s?
Show hintHide hint
Rearrange the formula to solve for time.
Question 6.
Calculate the angular displacement of a disk that starts from rest and accelerates uniformly at 4 rad/s² for 10 seconds.
Show hintHide hint
Make sure to consider that the initial angular velocity starts from rest.
