How Does Energy Transfer and Transformation Work?

Energy is like a toy that can change shapes but never disappears.

Imagine you have a bouncy ball, when you throw it on the floor, it bounces back up. That’s energy transfer: the energy from your hand moves to the ball, then the ball hits the floor, and the floor sends some of that energy right back.

Sometimes energy doesn’t just move, it changes form. This is called energy transformation.

Think about a slide at the park. When you run up the hill, you use your energy of motion (like when you’re running), and then you zoom down the slide, that’s energy of speed.

Or maybe you're on a swing: you push yourself to get higher, that's energy from your muscles, and as you go up, it becomes energy stored in height (called potential energy). When you come back down, that energy turns into speed energy again!

It’s like playing with blocks, you can stack them (store energy), knock them over (use the energy), or even roll them (change how the energy moves)!
