Relative motion is the calculation of the motion of an object with regard to some other moving object. Hence, relative motion is not a type of motion.
![A body of mass 20g projected vertically upwards in vacuum returns to the point of projection after 1.2s. [g = 10ms-2]. Determine the potential energy of the body at the maximum height of its motion. A body of mass 20g projected vertically upwards in vacuum returns to the point of projection after 1.2s. [g = 10ms-2].
