"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

Option A

Option B

Option C

Option D

Solution

When an object is thrown upwards its velocity is directed upwards but the acceleration is directed downwards. Therefore, velocity determines the direction of motion.
