Question

Which of the following statements is correct about motion with constant velocity?

• A. Acceleration of the body is zero.
• B. Acceleration of the body is non-zero.
• C. Velocity of the body is non-zero.
• D. Velocity of the body is necessarily zero.

Answer 1

Answer: (A), (C)

The correct options are
A Acceleration of the body is zero.
C Velocity of the body is non-zero.

In a motion with constant velocity, the velocity of the body is constant.
Acceleration is rate of change of velocity. Since velocity is constant, change in velocity is zero and acceleration is zero.

When the acceleration is non-zero, the magnitude of velocity will vary.
