Question

what is the difference between acceleration and velocity

Answer 1

Here it is:

Acceleration- The rate of change of velocity is called as acceleration.
Denoted by "a".
SI unit is m/s².

Velocity- The rate of change of displacement is known as velocity.
Denoted by "u" or "v" i.e., initial or final velocity.
SI unit is m/s.

Answer 2

Velocity is the rate of change of displacement and acceleration is the rate of change of velocity with respect to time
