1.Energy Transformations
Energy can only be transformed from one form to another. It cannot be created or destroyed. This is known as the law of conservation of energy which was created by Herman van Helmholtz. It is the first law of thermodynamics (Hakim). Energy Transformations can happen in single stages or multi-stages. An example of a single transformation is when a toaster converts from electricity or electrical energy to heat or thermal energy, which creates toast. An example of a multi-staged transformation is when a match is lit. When it is lit it creates thermal energy. The thermal energy burns away at the wood and that creates chemical energy. Then that makes a light which was made by Chemical energy to electromagnetic energy (Jones).

Transformations between potential and kinetic energy


There are two types of energy that apply to our life each day. They’re called potential energy and kinetic energy. An objects potential energy is its potential to move. Kinetic energy is basically the opposite of potential energy where it uses energy. An example of potential energy is elastic potential energy. An example of elastic potential energy is "an archer pulls back a bow, and elastic potential energy is stored in the taut bowstring,"(Snedden 7). Here are some pictures and a video that represent the change between potential and kinetic energy.

As kinetic energy decreases potential increases and vice versa (energy).
As kinetic energy decreases potential increases and vice versa (energy).
As the baseball's height increases the potential energy increases and vice versa (potential).

Conservation of Energy
Conservation of energy means energy cannot be created or destroyed, This is stated the law of conservation of energy.
The total amount of energy is the same before and after transformation. Whenever a moving object experiences friction some of its kinetic energy is transformed to thermal energy. Einstein realized that the law of conservation of energy and the law of mass conservation (a law that states matter cannot be created or destroyed) are related. He then combined them into the law of energy mass conservation which is one of the first laws of thermodynamics (Hakim).
