Question

Flowing water possesses

• A. kinetic energy
• B. potential energy
• C. electrical energy
• D. both (a) and (b)

Answer 1

The correct option is A

kinetic energy

Explanation for the correct option

Option A: kinetic energy

1. The energy possessed by a body by virtue of its motion is known as its kinetic energy.
2. The energy possessed by strong blowing winds, flowing water, a bullet fired, a fast-moving ball are some examples of energy due to motion.
3. Kinetic energy is directly proportional to the mass of the body and the square of the velocity with which it moves.

Explanation for the incorrect options

Option B: potential energy

1. The energy possessed by a body due to its position or change in shape is known as potential energy.
2. A stretched rubber band, a stretched bow, water in a dam, etc., are some examples where the body possesses potential energy.

Option C: electrical energy

1. Two charged bodies either attract or repel each other. And, if they are free to move, the charged bodies either move towards each other or move away from each other.
2. This happens because of energy possessed by a charged body called electrical energy.
3. Electrical energy is also required to move the electric charge (current) through a conductor, to run a T.V., machine, electric bell, etc.

Option D: both (a) and (b)

Flowing water possesses kinetic energy not potential energy. Thus both a and b can not be the answer.

Thus, the flowing water possesses only kinetic energy.

Hence, option (A) is correct.
