energy

Energy is the ability to do work. It is all around us, and it can take many different forms. Some common forms of energy include heat, light, electricity, and motion.

We use energy all the time, even when we don't realise it. For example, when we walk, we use the energy from the food we eat to power our muscles. When we turn on a light, we use the energy from electricity to make the light bulb glow.

Energy can be transferred from one form to another. For example, when we burn wood, the chemical energy in the wood is converted into heat energy. The heat energy can then be used to cook food, warm our homes, or generate electricity.

Energy can also be stored. For example, we can store electrical energy in batteries. We can also store energy in the form of food, which our bodies can then use to do work.

Energy can be found in many different forms, such as heat, light, and electricity.
