Question

In uniform circular motion, which of the following quantities are constant? Select all that apply.

a. The tangential component of acceleration instantaneous velocity.
b. The radial component of acceleration
c. The tangential component of velocity

Answer 1

In uniform circular motion, the tangential component of acceleration and the tangential component of velocity are constant.

Step-by-step explanation:

In uniform circular motion, the tangential component of acceleration and the tangential component of velocity are constant.

The tangential component of acceleration refers to the rate of change of the magnitude of the velocity and is responsible for changing the speed of the object. If the speed is constant, the tangential component of acceleration is zero.

The tangential component of velocity is the component of velocity that is parallel to the tangent of the circular path. Since the speed is constant in uniform circular motion, the tangential component of velocity remains constant as well.
