Conservation laws state that certain properties or quantities remain constant during physical processes, even though they may change form or be transferred between different objects or systems.
Energy cannot be created or destroyed; it can only be transferred or transformed from one form to another.
Conservation of Momentum: The total momentum before an event is equal to the total momentum after the event, as long as no external forces are acting.
The total angular momentum of a system remains constant if no external torques act on it.
