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.
a) Trees - They are at rest as they do not change their position with respect to their surrounding.
b) Flying bird - It is in motion as it is changing its position with respect to its surroundings and going from one place to another.
c) House - It is at rest as it is not changing its position.
d) Oscillating pendulum - It is in the state of motion as it is changing its position with respect to its surrounding.
e) Electricity poles - They are at rest as they do not change their position with respect to their surrounding.
