Define Uniform and Non Uniform motion .
Answers
When a body covers equal distances in a straight line, equal intervals of time are called uniform motion. Example: a car moving at 20km/h in a straight line. When a body covers unequal distance in equal intervals of time in a straight line is called non-uniform Example : spinning wheel.
hope it's help u
Uniform Motion:- the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
If a body is involved in rectilinear motion and the motion is consistent, then the acceleration of the body must be zero.
example - If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second.
Non Uniform Motion:- the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
If a body is involved in rectilinear motion, and if the motion is not consistent, then the acceleration of the body must be non-zero.
example - If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.
