Question

State whether the following objects possess kinetic energy, potential energy, or both:
(a) A man climbing a hill
(b) A flying aeroplane
​(c) A bird running on the ground

Answer 1

(a) A man climbing a hill posses only potential energy by virtue of his height with respect to the ground.

(b) An aeroplane flies at a great height from the ground with a super high speed, so we can say that a flying aeroplane has both the potential and kinetic energies.

(c) A bird running on the ground has only kinetic energy because of its motion.
