In Mt. Volta, there lived two types of people. The ones who saved their money and were always "potential" candidates for robbery and the "kinetics," a gang of young electrons that always liked to steal the "joules" from the calm, yet saving potential People. In a way, there always seemed to be the same number of joules between the two because every time the kinetics robbed from the potentials, they always seemed to spend joules at the stores of the potentials.
Similarly, Potential energy is stored energy (people who like to save their joules) and Kinetic Energy is energy being used.
Energy, when it is transferred, can be thought about in the following ways:
Electrical energy – The type which runs your mp3 players and personal electronics
Mechanical energy – What it takes to move something.
Heat energy – The warmth in your cup of hot chocolate.
Wave energy – These are the vibrations you feel from music or sound and make listening possible. More than sounds are wave energy.
In this case, you will be studying the energy involved with motion. In essence, there are two types of energy you will be studying:
Potential Energy (U) – The energy you store up. A measure of what could happen.
Kinetic Energy (K)-The energy you use.
Did you notice that both of the equations are the same? Well, you observed right because in the world there is this concept called "conservation of energy" which means no amount of energy is created or lost in the process. Similarly, we mentioned that Joules always seemed to be saved and spent at the same time. So, can we say
Potential Energy = Kinetic Energy
of course we can.
