Potential and kinetic

Did you know that there is two types of energy? One is called potential and the other is kinetic energy. Potential energy is stored energy that is ready to be used. Kinetic energy is moving energy like a ball being rolled down a hill. Now I'm going to tell you about them.

For example , a Newtons cradle shows these two types of energy. If you lift one of the balls up it is showing potential energy. You cannot see this energy until it is transformed into kinetic. If you let it go it will start moving and show kinetic energy.

There is always an opposite and equal reaction from every action, so the kinetic energy will run through the balls and it will cause an opposite reaction at the other side.

Feedback: I like your story HARRISON . Next time add a description Arlo.
Feed forward :good work but next time you could have a bit more information#hunter.
