When a body falls freely towards the earth,
Question:

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,

Solution:

(c) Total energy = K.E. + P.E.

When a body falls freely, its K.E. increases and P.E. decreases but the sum of K.E and P.E. remains the same.
