Question

When will you say a body is in:-

a) Uniform acceleration.

b) Non- Uniform acceleration.​

Answer 1

Answer:

Uniform Acceleration:- A body is said to have a uniform acceleration if it travels in a straight line and its velocity increases by equal amounts in equal intervals of time.

Eg.the motion of a freely falling body is uniformly accelerated.

The velocity-time graph of a body having uniformly accelerated motion is a straight line.

Non-uniform Acceleration:- A body is said to have a non-uniform acceleration if its velocity increases by unequal amounts in equal intervals of time.

Eg The speed or velocity of a car running on a crowded city road changes continuously.

The velocity-time graph of a body having uniform acceleration is a curved line.
