Define motion and explain the statement ‘Motion is a relative concept’ with an example.

Answer 1

Answer:

Relative motion is the calculation of the motion of an object with regard to some other moving or stationary object. ... For example, a person sitting in an airplane is at zero velocity relative to the airplane, but is moving at the same velocity as the airplane with respect to the ground.

Answer 2
