Energy is everywhere around us! It's what makes cars move, helps plants grow, keeps us warm, and powers every single thing that happens in the universe. But energy comes in many different forms, and it's constantly changing from one type to another.

What Is Energy?

Energy is the ability to make things happen - to cause motion, create heat, produce light, or make changes occur. You can't see energy itself, but you can see what it does. Think of energy as the invisible "fuel" that powers everything in our world!

THE AMAZING ENERGY LAW
Energy cannot be created or destroyed
Energy can only change from one form to another
The total amount of energy in the universe stays the same
When you use energy, you're actually transforming it!

Kinetic Energy: Energy of Motion

Kinetic energy is the energy that moving objects have. The faster something moves, the more kinetic energy it has. A speeding race car has much more kinetic energy than a slowly rolling ball. Even you have kinetic energy when you're walking, running, or riding your bike!

Potential Energy: Stored Energy

Potential energy is stored energy that's waiting to be used. Like a spring that's been compressed or a book sitting on a high shelf, potential energy is ready to become kinetic energy. When you climb to the top of a slide, you gain potential energy that turns into kinetic energy as you slide down!

ENERGY TRANSFORMATIONS IN ACTION
WIND-UP TOY: Your muscle energy becomes stored spring energy, then kinetic energy
EATING FOOD: Chemical energy in food becomes energy for your body
SOLAR PANELS: Light energy from the sun becomes electrical energy
WATER WHEEL: Moving water's kinetic energy becomes mechanical energy

Other Types of Energy

Energy comes in many forms: chemical energy stored in food and batteries, electrical energy that powers your devices, thermal energy that keeps you warm, light energy from the sun, and sound energy that lets you hear music.
