Types of Energy
By: Ronen Santiago
Kinetic Energy
The equation for kinetic energy is mv^2/2. The m stands for the object's mass in kilograms. The v stands for the objects speed.
Potential Energy
There is also gravitational potential energy. Books on a shelf have gravitational potential energy. The amount of gravitational potential energy that an object has depends on its weight and height. The equation for finding gravitational potential energy is weight times height.
Mechanical Energy
Thermal Energy
A lake has more thermal energy than steaming water because it has more particles. The steaming waters particles move faster than the lake because it has a higher temperature.
Electrical Energy
Fro example if you plug in an amplifier and turn it on. The electrons in the wires transfer to different parts of the amplifier. The electrons move to do work that makes you hear the sound from the amplifier.
