3 cards from this section. Quick, good the night before a test.
What is angular acceleration?
Think about how quickly something is speeding up or slowing down while rotating.
How is linear acceleration related to angular acceleration?
What do you multiply angular acceleration by to find linear acceleration?
What is the unit of angular acceleration?
Recall how we measure acceleration in rotational terms.
True or False: Linear acceleration can be calculated using the formula a = r · α.
Think about how they are connected.
An amusement park ride has a rotational acceleration of 1.5 rad/s². If the radius of the ride is 25 meters, what is the linear acceleration experienced by riders on the edge?
Focus on applying the relationship between angular and linear acceleration.
A disc rotates starting at 0 rad/s, accelerating uniformly at 3 rad/s². How many radians will it rotate after 5 seconds?
