the linear acceleration of a body moving in a circular path is:
Correct answer: D. zero
- A. negative
- B. positive
- C. constant
- D. zero
Explanation
Linear acceleration, also known as tangential acceleration, is zero when a body is moving in a circular path because the object has constant speed. (note: the question does not provide complete information. It should be mentioned in the question that the body is moving in a constant speed. Otherwise, linear acceleration exists in circular motion as well.)

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
