Question

Define a) uniform acceleration b) non- uniform acc. Give examples.

Answer 1

a) Uniform acceleration:-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.

b) non uniform acceleration:- A body has a non-uniform acceleration if its velocity increases by unequal amount in equal intervals of time. For Ex:Car running on a crowded city road(At one moment its velocity increases and at other velocity decreases.)
