Can Energy Change from One Form to Another?

Energy can change from one type to another, and this is an important idea in physics. Let’s look at some simple examples of how energy transforms:

Turning Chemical Energy into Kinetic Energy: In a car, gasoline is a type of chemical energy. When it's burned, it changes into kinetic energy, which makes the car move.
Changing Potential Energy to Kinetic Energy: A roller coaster at the top of a hill has potential energy. As it goes down the hill, that energy changes into kinetic energy, making it speed up.
Converting Electrical Energy to Light Energy: In a light bulb, electrical energy changes into light energy. This transformation gives us light to see.

Important Facts:

The way energy changes forms can be different. For example, regular engines use only about 25% of chemical energy to do useful work.
Around 90% of the world’s energy comes from fossil fuels. This shows how important it is to understand these energy changes in our everyday lives.
