Everyday examples can help us understand how energy changes and is saved. Here are some easy-to-understand examples:

1. Roller Coaster:

   • When the coaster is at the top, it has a lot of potential energy (PE).
   • As it goes down, that potential energy changes into kinetic energy (KE), which makes it go faster.

2. Bouncing Ball:

   • When the ball is at its highest point, it has high potential energy.
   • As it falls, that potential energy turns into kinetic energy until it hits the ground.

3. Light Bulb:

   • When you turn on a light bulb, electrical energy changes into heat and light energy. This shows energy transformation happening right in front of us.

4. Pendulum:

   • At the top of its swing, a pendulum has the most potential energy.
   • As it moves down, it keeps switching between potential energy and kinetic energy.

These examples show us that energy changes its form but is never lost. This is what we call the conservation of energy!
