Question 1
When a body falls freely towards the earth, then its total energy

(a) increases
(b) decreases
(c) remains constant
(d) first increases and then decreases

Open in App

Solution

(c) remains constant

Total energy of the body remains constant. The potential energy of the body gets converted into kinetic energy of the body but the total energy remains constant.
