Question

which is the difference between uniform velocity and non uniform velocity​

Answer 1

When a body moves with constant speed is said to be moving with uniform velocity.
For example if a body is moving with 10m/s and continue to move with this speed in the whole journey.


When a body changes its speed, the velocity of the body is non- uniform.
For example the body travels with 2m/s in first 2 seconds, with 5m/s in the next 4 seconds and with 10m/s in next 3 seconds then it is said to be moving with non-uniform velocity.
