Kinetic and Potential Energy
Energy: the ability to do work, HOWEVER in Science it means when force causes an object to move
There are many types of energy, but the main 2 types are Potential and Kinetic Energy. Potential Energy is energy waiting to be used, while Kinetic is the energy of movement. In the video below containing X2 at Six Flags, it will show how they are slowly moving up the tracks. It has Kinetic Energy, but there is some Potential Energy waiting to be used, such as the high speeds at which the people are going at later in the video. Because of going so fast, the ride is producing heat energy, formed by how fast kinetic energy is moving. Because of this, the wheels have insulators that make sure it doesn't get too hot.
