| Laws of Conservation |
|
| There are nearly 14 laws of conservation based on symmetry principles in physics. Anything that happens must not be forbidden by a conservation law, some of the important ones are: |
| |
| Laws of conservation of linear momentum |
| |
| If no external force acts on a system of colliding objects, then the total momentum before collision is equal to the total momentum after collision, in the same direction. |
| |
| Law of conservation of energy |
| |
| Energy can neither be created nor destroyed. It can only be transformed from one form to another. |
| |
| Law of conservation of angular momentum |
| |
| If no external torque acts upon a system, then the angular momentum of the system remains constant. |
| |
| Conservation of charge |
| |
| The total electric charge of an isolated system remains constant. |
