Q: An object undergoing circular motion experiences centripetal what?


Read this paragraph and choose the correct option from the provided answers:

Linear or tangential acceleration refers to changes in the magnitude of velocity but not its direction. We know from Uniform Circular Motion and Gravitation that in circular motion centripetal acceleration, a c , refers to changes in the direction of the velocity but not its magnitude. An object undergoing circular motion experiences centripetal acceleration, as seen in Figure 10.5. Thus, a t and a c are perpendicular and independent of one another. Tangential acceleration a t is directly related to the angular acceleration.

 Choices:

- velocity

- vibration

- transmission

- acceleration


A:
acceleration
