Explain uniform acceleration and non-uniform acceleration.

Acceleration is the rate of change of velocity 

If the velocity of the moving object is non-uniform, it implies that the object is accelerating but if the object is moving with an equal change in the velocity in equal interval of time then it is said to be having an uniform acceleration.

If the rate of change of velocity is not uniform then the object is said to be moving with non-uniform acceleration.

Final Answer: Hence, an object moving with equal change in the velocity in equal interval of time is moving with an uniform acceleration else with a non-uniform acceleration.
