Question

When a person climbs a hill, he possesses

• A. only K.E.
• B. only P.E.
• C. both K.E. and P.E.
• D. neither K.E. nor P.E.

Answer 1

The correct option is C

both K.E. and P.E.

1. When a person climbs a hill, his distance (height) from ground level increases and he moves against gravity. Thus, he possesses potential energy (P.E.) due to his position above ground level.
2. As he climbs the hill with some velocity, the person also possesses kinetic energy (K.E.) due to his motion.

Thus, a person climbing a hill possesses both K.E. and P.E.

Hence, option (c) is correct.
