define uniform and non-uniform velocity. How much acceleration is produced on an object at uniform motion, why?​ Pls answer my question anyone pls!

when a body covers equal distance in equal interval of time with a known direction, small the interval may be then velocity is said to be uniform velocity.

when an object covers unequal distance in a specified direction is said to be non-uniform velocity.

It produce zero acceleration as acceleration is defined as the rate of change of velocity per unit time. So, if the body exhibit uniform velocity,then the rate of change of velocity (dv=0) will be zero.

This answer may help u .

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.
