4 cards from this section. Quick, good the night before a test.
Define angular velocity and give its SI unit.
What unit do we commonly use for speed or velocity?
What does the symbol ω represent?
Consider the relevant physics quantities related to rotation.
What is the unit of angular velocity?
Consider what units are used in circular motion.
True or False: Angular acceleration can be negative.
Think about what happens to speed when deceleration occurs.
A merry-go-round is rotating at an angular velocity of 2 rad/s. If it accelerates at a rate of 0.5 rad/s², calculate how long it will take to reach an angular velocity of 6 rad/s.
Rearranging the formula can help solve for time.
A basketball player spins around while dribbling, increasing her rotation speed at 1.5 rad/s². If she starts from rest, what is her angular velocity after 4 seconds?
Calculate the final velocity using the acceleration over time.
