Question

1) define rest and motion

2) define distance and displacement. write their S.I unit.

Answer 1

an object which is in rest position .
an object which is moving is called in motion or kinetic
distance is a scalar quantity eg. East West North South
displacement is a vector quantity or shortest distance or straight line.

Answer 2

Answer:

Rest: An object is said to be at rest if it does not change its position with respect to its surroundings with time.

Motion: An object is said to be in motion if the position changes with respect to it surrounding and time.

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude.
