Conservation of Energy and Work-Energy Theorem
... frictional and drag forces do not act on the objects in the system. Also, we shall assume that the system is isolated from its environment i.e. no external force from an object outside the system causes energy changes inside the system. When a conservative force does work W on an object within the s ...
