Question

Define uniform acceleration and non-uniform velocity.

Answer 1

uniform Acceleration - A body has a uniform acceleration if it travels in a straight line and its velocity increases by equal amounts in equal intervals of time. Non-Uniform Acceleration - A body has a non-uniform acceleration if its velocity increases by unequal amounts in equal intervals of time.

Answer 2

UNIFORM ACCELERATION

• Uniformly accelerated motion - If a body travels in a straight line and its velocity increases in equal amounts in equal intervals of time . Its motion is known as uniformly accelerated motion.

• For example motion of a freely falling body is an example of uniformly accelerated motion ( or motion of a body under the gravitational pull of the earth ).

NON-UNIFORM VELOCITY

• When a body does not cover equal distances in equal intervals of time, in a given direction( in this case speed is not constant) , then it is known as non- uniform velocity. If speed is constant then also body can have a non- uniform velocity.

• For example, a car moving on a circular road with constant speed .
