Give a real-life example of anything with high potential energy (not including roller coasters).
Many correct answers, but for example a diver on the high diving board at a swimming pool.
Give a real-life example of anything with high kinetic energy (not including roller coasters).
Many correct answers, but for example a car driving very fast down the high way.
A truck is going very fast down the highway, and hits the breaks hard to avoid hitting the car in front of him. The kinetic energy was converted into this
