Question

define uniform motion and non-uniform motion? Give an example of non -uniform motion.

Answer 1

Uniform motion is that motion in which a body travells equal distance in equal intervals of time.
For example a body is moving 1 m in 1s, 2m in 2s, 3m in 3s and so on.

Non uniform. Motion is that motion in which body travells unequal distance in intervals of time.
For example body is moving 1m in 1s, 2m in 5s 3m in 7s and so on.

Answer 2

When a body travels equal distance in equal intervals of time, then the body is to have a uniform motion.
When a body travels in equal distance in uninterval of time, then the body is said to move in Non-Uniform motion.
