Question

define uniform and non-uniform acceraltion.​

Answer 1

Answer:

A body has a uniform acceleration if it travels in a straight line and its velocity increases by equal amount in equal intervals of time. For Ex:Motion of freely falling body, bicycle going down the slope, ball rolling down in inclined plane

A uniform acceleration is a motion in which the change in velocity with time is linear or uniform.

A non-uniform acceleration is a kind motion of motion in which the change in velocity with time is not linear or uniform.

Answer 2

Answer:

Non-uniform acceleration constitutes the most general description of motion. It refers to variation in the rate of change in velocity. Simply put, it means that acceleration changes during motion. This variation can be expressed either in terms of position (x) or time (t).

If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn't have uniform acceleration.
