Energy Input and Output
By:Joshua, Om and Gabriel
Energy
According to Google,The capacity or power to do work, such as the capacity to move an object (of a given mass) by the application of force.
Our definition-The property that is transferred to work on or apply heat on,this might also exist in
different forms such as electrical energy,light energy,kinetic energy,potential energy,chemical energy and so on...

We realized that we have more input energy than output energy.
Our snacks seems to have the biggest effect on our diet.
Transfer of Energy
Transfer of Energy
The law of conservation of energy states that energy cannot be created nor destroyed, it can only be transformed or transferred from one form to another. Energy is transferred from one form to another when a reaction takes place. Some of the ways energy gets transferred is by conduction, convection, radiation, potential, kinetic and chemical energy.
