Apply Principle of Conservation of Energy to rotational situations.
In order to transform of transfer energy we must do WORK
W= Fd
W= Fd
In rotational mechanics the idea is the same but formula relates to our angular quantities:
Work = Torque x angular displacement
Work = Torque x angular displacement
The Bouncing Tic Tac
The Bouncing Tic Tac
When you increase the height you drop a ball from you increase the gravitational potential energy. But because of the energy lost due to friction it never bounces back to the same height. So how is it that a tic tac's second bounce is higher than its first? Watch Physics Girl explain:
