Question

1) What is mean by motion & rest ?

2) What are Uniform and non uniform motions ? Give examples.
who answers first i will mark brainlist ​

Answer 1

1. Rest and motion are relative terms. ... In simple terms, an object that changes its position is said to be in motion while the opposite action causes an object to be at rest.

2. The type of motion in which the object travels with a varied speed is called Non-Uniform Motion. This means that the object does not cover the equal distance in equal time intervals. ... For example, the motion of a vehicle, an oscillation of a pendulum. Non-uniform motion is also called accelerated motion.

Examples of Uniform Motions.

A car going along a straight level road at steady speed.

Example of non uniform motions.

The motion of a vehicle, an oscillation of a pendulum.

Answer 2

Answer:

Motion: motion is the phenomenon in which an object change its position over time.

Rest:An object said to be rest when a body doesn't change its position with respect to its surrounding and time.

Uniform motion: uniform motion is defined as the motion, where the velocity of the body traveling in a straight line remains the same.

example; a car going along a straight level road at steady speed.

Non uniform motion: Non uniform motion is used to mean the movement in which the object does not cover the same distance in the same time intervals

example;plane moving through the clouds and then landing.
