When will you say a body is in:-
a) Uniform acceleration.
b) Non- Uniform acceleration.
Answers
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.
