General Science (CHSL) Physics

Hydroelectric power stations generate electricity by using the force of water that falls into the turbines and spins the shaft. By

rotating the shaft of the turbine, the potential energy of water is converted into ________ energy.

chemical

thermal

gravitational

kinetic

Let’s break it down:

- Hydroelectric power stations take water at a height—full of potential energy.

- As water drops, it spins turbine blades.

- That spinning is kinetic energy—moving energy—turning the shaft connected to a generator.

- Here’s how the other options stack up:

- Chemical energy is about stored energy in fuels, like coal or batteries. Not what’s happening here.

- Thermal energy would mean heat. We’re not using heat, just moving water.

- Gravitational potential energy is what the water starts with, but the process is about turning it into something else—motion.

So, Option:4–kinetic is correct.
