Potential Energy is the energy that is stored in a elevated object. An example of this is a drawn bow because if the bow is not drawn, it would not have energy so when it is drawn, energy is stored.
Kinetic Energy is energy that is in motion. An example of this is a roller coaster. The most common kinetic energy for physics is called translational kinetic energy. This is energy that is depended on mass and speed.
Conservation of Energy
This law states that energy cannot be created or destroyed. The equation used for this is PE=mgh. The P stands for potential energy and the mgh stands for mass, acceleration due to gravity, and height.
