Uniform velocity: A body is said to be moving with uniform velocity if its average velocity between any two points along its path is the same in magnitude as well as direction.
Or
A body is said to be moving with uniform velocity is it always moves in the same direction and covers equal distances in equal intervals of time, however small these intervals may be.
Instantaneous velocity: When a body is moving with variable velocity, then its velocity at a particular instant of time or at a particular point along its path is known as its instantaneous velocity. It is equal to the limiting value of average velocity as dt tends to zero.
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, andaverage velocity can be defined as the displacement divided by the time.
