Question

when will you say a body is in-: a) Uniform motion b) non uniform motion

Answer 1

AnswEr :-

A body is said to be in Uniform motion when it covers equal distances in equal intervals of time.

A few examples of Uniform motion are – Rotation and revolution of earth, movement of the blades of a fan etc.

Also, the distance-time graph of uniform motion shows straight line.

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

A body is said to be in Non-Uniform motion when it covers unequal distances in equal intervals of time.

A few examples of Non-Uniform motion are – Oscillation of pendulum, a running person etc.

Also, the distance-time graph of non-uniform motion shows curved line.

Answer 2

Answer:

when a body covers equal distance in equal intervals of tike.then it said to be in uniform motion

and

when a body covers unequal distance I'm equal intervals of time then it said to be in non uniform motion
