2 cards from this section. Quick, good the night before a test.
What is the linear displacement of a point on a rotating wheel if the radius is 2 meters and the angle is π radians?
Use the formula s = r * θ.
If a wheel has an angular velocity of 3 rad/s and a radius of 1.5 meters, what is the linear velocity?
Recall v = r * ω.
What is the relationship between linear displacement and angular displacement?
Think about how the distance relates to the angle rotated.
True or False: Angular velocity is independent of the radius of rotation.
Consider the effects of radius on linear motion.
A speeder bike has wheels of 0.6 meters radius. If the bike accelerates from rest to an angular velocity of 10 rad/s in 2 seconds, calculate the linear velocity and linear acceleration of a point on the outer edge of the wheel.
Use the principles of linear motion combined with angular speed.
A turntable rotates at 30 rad/s. Calculate how far a point on its edge moves in 5 seconds and its angular acceleration if it comes to a stop in 10 seconds.
Use angular to linear transformations along with distance and time.
