When a body moves with a constant velocity, the average velocity and the instantaneous velocity are unequal.
Solution:
This statement is false.
Instantaneous velocity is the velocity at any given instant in time. Average velocity is calculated by dividing the total displacement of the object by the total time taken during the motion.
When a body moves with a constant velocity, the average velocity and the instantaneous velocity are equal. The body is said to be in uniform motion in this case.
