Conservation Energy Lab
... Conservation of Energy means that you cannot create nor destroy energy it is said to be transformed. So, the sum of the kinetic and potential energy everywhere is the same and that the total energy of an object remains constant. As the potential energy is increased by an increase in its height above ...
