Question
What do you understand by the terms
1. rest
2. motion? Support your answer by giving two examples each

Answer

(i) Rest: A body is said to be at rest if it does not change its position with respect to its immediate surroundings.
For example:
(a) A chair lying in a room.
(b) A stone lying on the ground.
(ii) Motion: A body is said to be in motion if it changes its position with respect to its immediate surroundings.
For example:
(a) A car running on the road.
(b) A football moving on the ground.
