Question

Which of the following pair of quantities cannot be simultaneously non-zero and constant for a body?

• A. Speed and velocity
• B. Distance and displacement
• C. Velocity and acceleration
• D. None of these

Answer 1

The correct option is C

Velocity and acceleration

Both acceleration and velocity cannot be simultaneously non-zero and constant.

If the acceleration is constant, the velocity changes and if velocity constant, acceleration is zero. (Zero is a constant, but its asked for a non-zero constant)
