Rama plays cricket with his friends every evening. Which energy does he use to…

Energy is the capacity to do work, and it is classified into different forms based on the process that produces or uses it. Muscular energy is the mechanical energy generated when muscles contract and relax, converting the chemical energy stored in food into the physical force and movement of the body.

When Rama plays cricket, running between the wickets, swinging the bat, and throwing the ball all require his muscles to contract repeatedly. This bodily movement and exertion is powered by muscular energy, so muscular energy is the correct classification for the energy Rama uses during the activity.

Why the other options do not fit:

• Light energy is the energy carried by electromagnetic radiation from a luminous source such as the sun or a lamp, and it enables vision — it plays no role in producing bodily movement.

• Chemical energy is stored in the bonds of substances such as food and is released during metabolic reactions; it is the underlying fuel source, but the immediate energy of movement itself is muscular energy, not the stored chemical form.

• Sound energy arises from the vibration of an object and travels as pressure waves through a medium; it is a byproduct of certain actions, such as a bat striking a ball, not the energy that powers muscle movement.

Therefore, the energy Rama uses to play cricket is muscular energy.
