Energy transformation is something we see every day, and it's really interesting to notice how it follows a basic rule: energy cannot be created or destroyed. Instead, it just changes from one form to another. Here are some easy examples from real life:
Roller Coasters: When a roller coaster goes up a hill, it gains energy called gravitational potential energy. As it goes down, this energy changes to kinetic energy, which makes the coaster go faster.
Bicycles: When you ride a bike, your muscles use energy from the food you eat. This energy turns into mechanical energy that helps move the bike forward.
Light Bulbs: A light bulb changes electrical energy into light energy. Even though some energy is lost as heat, it starts as electrical energy and changes into both light and heat.
Batteries: Batteries take chemical energy and turn it into electrical energy. For example, when you charge your phone, that’s energy transformation happening right in front of you!
In each of these examples, the total amount of energy stays the same. It’s a cool reminder that energy is always changing forms, but it never goes away!
