Given the question: Answer the following question given this paragraph: 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. Q: An object undergoing circular motion experiences centripetal what? Choices: - velocity - vibration - transmission - acceleration A:
The answer is:
acceleration
