Which are the conservation laws in physics ? Write them.

Explanation

`to` There are four laws of conservation in physics :
(1) Law of conservation of energy
(2) Law of conservation of electric charge
(3) Law of conservation of linear momentum
(4) Law of conservation of angular momentum
(1) Law of conservation of energy : The amount of total energy in the universe remains constant. Energy can neither be created nor be destroyed. It can just be converted from one form to another.
(2) Law of conservation of electric charge : During any process taking place in an electrically isolated system the algebraic sum of the charges always remains constant.
(3) Law of conservation of linear momentum : If the resultant external force on a system is zero the total linear momentum of the system remains constant.
(4) Law of conservation of angular momentum If the resultant external torque acting on a system is zero, the total angular momentum of the system remains constant.
