Example: I take an object of mass m = 1 kg and raise it to the height
... Li = m vi ri = m vf rf = Lf So, if rf < ri, then vf > vi to keep L constant. What about energy conservation? Since it is now going faster isn’t the kinetic energy increased? The kinetic energy is indeed increased, because we did work on the system. Work = F d ≈ (m v2/r) d This is energy we added to ...

... Work W is energy transferred to or from an object by means of a force acting on the object. If the object is accelerated by applying a force, its kinetic energy K increases. Energy transferred to the object is positive work +W. If you decelerate the object by applying a force, you decrease its ...
