Solution
Two examples in which the body possesses kinetic energy as well as potential energy are-
(i) A man climbing a hill
(ii) A bird flying in the sky
In both of the above examples, we can observe that the body has speed and its position is above the ground. Therefore, these bodies have kinetic and potential energy.
