answer detail explain uniform and non uniform motion with examples
Answers
Answer ッ
Uniform Motion: This type of motion is defined as 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 of Uniform Motion:
- 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.
- Movement of blades of a ceiling fan
Non Uniform Motion:
This type of motion is defined as 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 of Non Uniform Motion:
- If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.
- The motion of a train.
Now, people usually get confused between uniform motion and uniform acceleration. In the later phenomena, the object is having a constant acceleration in rectilinear motion, which means the object has different speed in every second ,which clearly defines that motion is changing.

♨ Uniform Motion:-
It is when the body travels equal distance in equal intervals of time.
☑ Example:-
A car running at constant speed 10 metres per second, will cover equal distances of 10 metres every second.
♨ Non uniform Motion:-
It is when the body travels unequal distances in equal intervals of time.
☑ Example:-
A ball dropped from roof of a tall building travels unequal distances in equal interval of time.
