Question

Examples of rest and motion in our daily life.

Answer 1

Hint:A body is said to be in rest which does not move with respect to time from one place to another. Whereas a body is said to be in motion if it changes its position with respect to time. Reference frame is necessary to declare a body as in the state of rest or motion.

Complete step-by-step solution:
Rest is defined as a state where the body does not move with respect to a reference frame with time. Examples of rest in our daily life are-
(i) A book lying on a table.
(ii) A clock hanging on the wall.
(iii) A chair in a room.
(iv) A person sitting on a chair.
(v) A flower pot in the garden.
(vi) A car parked in a parking area.
(vii) A fan switched off in the ceiling.
(viii) The walls of a building or the building itself.
(ix) A wardrobe in the house.
(x) A table in an office.
Motion is defined as a state which changes its motion with respect to a reference frame. Examples of motion in our daily life are-
(i) A man bicycling on a road.
(ii) A moving car on a road.
(iii) A person running in the alley.
(iv) A person walking on the road.
(v) A train running on its track.
(vi) Clouds moving in the sky.
(vii) A bee flying.
(viii) A leaf falling from the tree.
(ix) A bird flying upon the sky.
(x) Any object moving in running water.

Note:There isn't any object in the world which is in absolute rest as it is moving with respect to the Sun or any celestial bodies. Reference frame decides whether an object is in the state of rest or motion. For example, a person inside a running train is in motion with respect to the surroundings but in the state of rest with fellow passengers.
