what is uniform motion and non uniform motion
Answers
The motion is said to be uniform when a body covers equal distance in equal time, whereas in non uniform motion the body covers unequal distance in varied time intervals.
Explanation:
- In uniform motion the body moves in a straight line and the velocity of the body remains constant.
- That's why the body covers equal distance in equal time intervals.
- The acceleration on the body in this type of motion is zero.
- The type of motion followed by thus body us also called as rectilinear motion.
- The distance time graph for this type of motion is a linear graph.
- Example of uniform motion can be: motion of blades of ceiling fan, motion of arms of the watch, etc.
- In non uniform motion the body in motion is not covering equal distance in equal time intervals.
- Therefore, its velocity is not constant, and the acceleration is not zero.
- The distance time graph obtained for such motions is curved.
- Examples of non uniform motion includes motion of a car on a busy road with traffic.
Answer:
A body is said to exhibit uniform motion if it covers equal distances in equal intervals of time. For example, the motion of a motor bike moving along a straight road such that it covers equal distances in equal intervals of time, say per second it covers a distance of 15 metres is uniform motion.
A body is said to exhibit non-uniform motion if it covers unequal distances in equal intervals of time. For example, the motion of a car moving on a busy road such that it covers unequal distances in equal intervals of time, say it covers first 10 metres in 3 seconds, next 15 metres in 3 seconds and next 20 metres in 3 seconds.
NOTE : If a body covers equal distances in equal intervals of time but its direction is not constant, then also its motion is considered to be non-uniform.
