State whether the following objects possess kinetic energy, potential energy, or both:

(a) A man climbing a hill


(b) A flying airplane


(c) A bird running on the ground


(d) A ceiling fan in the off position


(e) A stretched spring lying on the ground.

(a) Potential energy and kinetic energy to (Since the person is gaining height along with velocity)

(b) Kinetic energy and potential energy (Since the airplane ​ poses motion and height both)


(c) Only kinetic energy (Since the bird do not poses height but velocity)


(d) Only potential energy (Since the fan is at height and not moving)


(e) Only potential energy (Rather elastic potential energy). (As it do not poses motion)
