"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.
(N/A) When an object is thrown vertically upwards, its velocity is directed upwards because it is moving away from the ground. However, the acceleration due to gravity $(g)$ acts downwards towards the center of the Earth. Since the object continues to move upwards despite the downward acceleration, it proves that the direction of motion is determined by the velocity and not by the acceleration.
