... In physics, energy is defined as the capacity of a physical system to do work. This can be measured by the amount of work done. Scientists often relate this to the amount of force needed to move an object of a given mass a given distance. For example, if you inflated your balloon to a diameter of tw ...

... Two kinds of non-conservative forces: Applied forces: Forces that are external to the system. These forces can take away or add energy to the system. So the mechanical energy of the system is no longer conserved. If you were to carry around a ball, the force you apply to the ball is external to the ...
