•  Conservation Law of Physics

1) Conservation Law of Energy

2) Conservation Law of Linear Momentum

3) Conservation Law of Angular Momentum

4) Conservation Law of Charge

- Conservation Law of Energy :

 The law of conservation of energy states that energy can neither 

 be created nor destroyed – it transforms from one form to another

- Conservation Law of Linear Momentum :

  If the net external force acting on a system of bodies is zero, then

  the momentum of the system remains constant.

- Conservation Law of Angular Momentum :

  For a spinning system, there is no change in the angular momentum of

 The object until and unless n external torque is applied to it.

- Conservation Law of Charge :
   

  the total amount of electric charge in a system does not change

  with time.
