If a body is moving with constant speed, then its acceleration

Question

If a body is moving with constant speed, then its acceleration (A) Must be zero (B) May be variable (C) May be uniform (D) Both (2) (3)

Tardigrade Admin · Accepted Answer

Acceleration is the rate of change of velocity. The magnitude of velocity (i.e., speed) is constant but it may change in direction. So, acceleration may be variable due to change in direction

Q. If a body is moving with constant speed, then its acceleration

Must be zero

May be variable

May be uniform

Both (2) & (3)

Acceleration is the rate of change of velocity. The magnitude of velocity (i.e., speed) is constant but it may change in direction. So, acceleration may be variable due to change in direction
