Conservation of Energy
Conservation of Energy
Apply Principle of Conservation of Energy to rotational situations.
In order to transform of transfer energy we must do WORK
In rotational mechanics the idea is the same but formula relates to our angular quantities:
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:
