CONSERVATION LAWS
In any physical phenomenon governed by several different forces, several quantities may change with time.However, some physical quantities remains constant in time.These quantities are the 'conserve quantities' of nature.This remarkable fact is the basis of many law called conservation laws. There are nearly 14 conservation laws based on symmetry principle on Physics.And from those 14 laws discussion of some of the laws are given below: Law of conservation of linear momentum If no external force acts on system of colliding objects, then the total momentum of the objects, in a given direction before collision is equal to the total momentum of object in same direction after collision. 2. Law of conservation of mass energy when a body falls freely in vacuum under the effect of Earth's Gravity, the total mechanical energy (sum of kinetic and potential energy) remains constant. Both the kinetic and its potential energy change continuousl...
