Question

If a body is moving at constant speed in a circular path, its:
(a) velocity is constant and its acceleration is zero
(b) velocity and acceleration are both changing direction only
(c) velocity and acceleration are both increasing
(d) velocity is constant and acceleration is changing direction

Answer 1

b. velocity and acceleration are changing direction only

Answer 2

Answer:

b) velocity and acceleration are both changing direction only

Explanation:

In a circular motion , the direction of motion is along the tangent of the circle and hence the direction changes every moment . Since velocity and acceleration are dependent on direction . Hence , the velocituly and acceleration are only changing direction .
