"The direction in which an object moves is given by the direction of velocity of the object and not by the direction of acceleration". Give an example to justify this statement.

Velocity is the rate of change of displacement which shows how fast an object changes its distance and its direction. Acceleration is rate of change of velocity which shows how fast an object changes its velocity.

For example;

Suppose a car is moving in the positive direction with acceleration ‘a’.


If we apply breaks the car slows down. Due to this its acceleration becomes negative i.e. ‘-a’. However, the motion of the car remains in forward direction.
