You can see the Work-Energy Principle all around us! Here are a few easy examples:
Roller Coasters: When the coaster is at the highest point, it has a lot of potential energy. As it goes down, that energy changes into kinetic energy, which makes it go faster!
Kicking a Soccer Ball: When you kick the ball, your foot does some work on it. This moves energy from your foot to the ball, making it fly through the air.
Braking a Car: When you press the brakes, the car slows down. The kinetic energy of the car turns into heat because of friction, which helps to stop the car.
These examples show how energy changes when work is done!
