Which statement about acceleration is correct?
AAcceleration is the rate of change of distance with time
BAcceleration is always opposite to velocity
CAcceleration is the rate of change of velocity with time
DA body moving with constant velocity has constant non-zero acceleration
Answer & Solution
Correct answer: C. Acceleration is the rate of change of velocity with time
Acceleration is defined as change in velocity per unit time. If velocity is constant, neither its magnitude nor direction changes, so acceleration is zero.
