Question

define velocity with example

Answer 1

Displacement per unit time of amoving body is known as velocity.
velocity≈Displacement/time m/sec

Answer 2

velocity of a body is defined as the displacement of the body in unit time. We can get the velocity by dividing displacement by time taken.

example: if s body's displacement is 6m in 2 second,
velocity=6/2 = 3 m/s
