Question

a)What is meant by conservation law in physics?
b) Define the Given laws in your words
1. Law of conservation of energy
2. Law of conservation of charge
3. Law of conservation of linear momentum
4. Law of conservation of Angular momentum​

Answer 1

Answer- a

Conservation Law- Those quantities which remain conserved in nature are known as conserved quantities and the physics which deals with those physical quantities laws are known as conservation law.

Answer- b

1. Law of conservation of energy- According to this law total energy remains constant or conserved in a system.

2. Law of conservation of charge- According to this law in an isolated system total charge is conserved.

3. Law of conservation of linear momentum- According to this linear momentum remains constant in a system without any external force.

4. Law of conservation of Angular momentum- According to this law angular momentum remains constant in the absence of any external torque in the system.

A particular measurable property of an isolated object isolated physical system does not change as the system evolves over time is called Conservation law

_________________________

$\to$ Law of conservation of energy states that energy can neither be created nor be destroyed

$\to$ Law of conservation of charge states that charge can be distributed between the different bodies but it can't be created or destroyed

$\to$ Law of conservation of linear momentum states that total momentum before collision is equal to the total momentum after collision

$\to$ Law of conservation of angular momentum states angular momentum is conserved when there is zero net torque force applied to a system
