Choose the correct statement:

Options

A. Unit of acceleration is `ms^(-2)`
B. Speed = distance/time.
C. If a body moves with uniform velocity, its acceleration is zero.
D. All of the above

Answer

D

Explanation

(1) Unit of acceleration is m `s^(-2)`
(2) Speed = `("distance")/("time")`
(3) As the body is moving with uniform (constant) velocity, i.e., there is no change in the velocity of body, and hence, acceleration of the body = zero.
