Energy is the ability to make things move, work, or change.

It is essential for everything we do, from playing to studying.

Energy can come from many sources, such as food, sunlight, electricity, and fuels.

All living things and machines rely on energy to operate.

Energy is often invisible, but we can see its effects.

For example, when you eat food, your body converts that food into energy.

This energy helps you run, jump, and play.

Similarly, when the sun shines, it provides solar energy that plants use to make food through a process called photosynthesis.

There are different types of energy, including mechanical energy, thermal energy, and light energy.

Mechanical energy helps objects move, like a rolling ball.

Thermal energy is heat, like when your hands warm up by the fire.

Light energy allows us to see, like when a light bulb shines in a dark room.

Energy also changes forms.

When you turn on a light switch, electrical energy converts into light energy.

When you ride a bicycle, your muscles convert chemical energy from food into motion.

This energy transformation helps us perform daily activities efficiently.

Did you know that energy cannot be created or destroyed?

It can only change from one form to another.

Also, energy is measured in units called joules.
