Law of conservation of momentum states that unless an external force is applied, the two or more objects acting upon each other in an isolated system, the total momentum of the system remains constant. … Now, elastic collision occurs between these bodies because we have assumed u1>u2.

## What is conservation of linear momentum give two example?

1) When a bullet is fired from a gun, the recoil of the gun can be explained on the basis of the law of conservation of linear momentum. 2) When a heavy nucleus at rest disintegrates into two smaller nuclei, the products move in opposite directions, obeying the law of conservation of linear momentum.

## What is law of conservation of linear momentum Class 11?

The law of conservation of linear momentum states that if no external forces act on the system of two colliding objects, then the vector sum of the linear momentum of each body remains constant and is not affected by their mutual interaction. … Therefore, ‘P’ is constant or conserved.

## What do you mean by conservation of linear momentum explain it giving appropriate example?

Conservation Of Linear Momentum Example Two bodies of mass M and m are moving in opposite directions with the velocities v.If they collide and move together after the collision, we have to find the velocity of the system. Since there is no external force acting on the system of two bodies, momentum will be conserved.

## What is conservation of momentum prove it?

Law of conservation of momentum states that total momentum of system remains conserved in the absence of external force. Proof: Consider a body of mass m1 moving with velocity U1, striking against another body of mass m2 moving with velocity U2.

## What is conservation of linear momentum write the formula?

Linear momentum is a product of the mass (m) of an object and the velocity (v) of the object. If an object has higher momentum, then it harder to stop it. The formula for linear momentum is p = mv. The total amount of momentum never changes, and this property is called conservation of momentum.

## What is conservation of linear momentum Class 9?

Answer: The principle of conservation of momentum states that if two objects collide, then the total momentum before and after the collision will be the same if there is no external force acting on the colliding objects.

## What is the importance of conservation of linear momentum?

What is the Significance of Linear Momentum? Ans- The significance of conservation of linear momentum of a system or body in motion is that it retains the total momentum and is equal to the product of mass and vector velocity, provided there is an application of external force acting in it.

## What is law of conservation of momentum answer?

Law of conservation of momentum states that. For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.

## What is linear momentum Class 9?

Linear momentum is the vector quantity and defined as the product of the mass of an object, m, and its velocity, v. The letter ‘p’ is applied to express it and used as momentum for short. … It’s a conserved quantity which means that the total momentum of a system is constant. The units of linear momentum are kg m/s.

## What is an example of the law of conservation of momentum?

An example of law of conservation of momentum is Newton’s cradle, a device where, when one ball is lifted and then let go, the ball on the other end of a row of balls will push upward.

## What is the necessary and sufficient condition for conservation of linear momentum?

A system must meet two requirements for its momentum to be conserved: The mass of the system must remain constant during the interaction.As the objects interact (apply forces on each other), they may transfer mass from one to another; but any mass one object gains is balanced by the loss of that mass from another.

## What is linear momentum prove law of conservation of linear momentum with clear explanation diagram and equation?

m1v1-m1u1=-m2v2+m2u2. m1v1+m2v2=m1u1+m2u2. this is the law of conservation of momentum.

## How do you calculate the principle of conservation of momentum?

The equation pf = pi says that when you have an isolated system with no external forces, the initial total momentum before a collision equals the final total momentum after a collision, giving you the principle of conservation of momentum.

## What is conservation 9th standard?

Conservation means usage, improvement, protection of human and natural resources in a wise manner. … Our Natural Resources should be conserved because it is the main source of our daily needs and is limited only. If these resources are abused and harmed, we will have a short quantity of sources for food and living.

## What is the difference between conservation of momentum and conservation of linear momentum?

There is no difference in both of them. Both are same.

## What does the principle of conservation of linear momentum state?

(a). The linear momentum of a system cannot be changed. (b). The linear momentum of a system cannot remain constant. … The law of conservation of momentum states that the momentum of the body remains constant until and unless any external force acts on it.

## What is the nature of law of conservation of linear momentum?

The Law of conservation of linear momentum is a vector law. It implies that both the magnitude and direction of total linear momentum are constant. In some cases, this total momentum can also be zero. 2.
