Question

state law of conservation of momentum ​

Answer 1

Answer:

state law of conservation of momentum

• the law of conservation of momentum states that when the external force applied on a body is zero
• then the initial Momentum will be equal to the final momentum
• in other words the momentum will be conserved
• it is only applied where the external force in a particular direction of the net force is zero

Answer 2

Answer:

here is ur answer frnd

Explanation:

The law of conservation of momentum states that for two objects colliding in an isolated system, the total momentum before and after the collision is equal. This is because the momentum lost by one object is equal to the momentum gained by the other.

Conservation of momentum is derived from Newton's laws of motion. Newton's third law states that every action has an equal but opposite reaction; the force that one object A exerts on object B is equal but opposite to the force that object B exerts on object A. By Newton's second law, this force is equal to the product of the mass and the acceleration of the objects, so the product of the mass and acceleration of object A is equal but opposite to the product between the mass and acceleration of object B.

system of gun and a bullet. Before firing the gun, both the gun and the bullet are at rest, so the total momentum of the system is zero. As the gun is fired, bullet shoots out of the gun and acquires momentum. To conserve the momentum of the system, the gun recoils. According to the law of conservation of momentum, the total momentum of the gun and the bullet will be zero after the gun is fired. Let m be the mass of the bullet and v be the velocity on firing the gun; M be the mass of the gun and V be the velocity with which it recoils. Thus the total momentum of the gun and the bullet after the gun is fired will be:

The total momentum of gun and bullet after the gun is fired = M v + m v ….(1)

example of law of conservation of momentum is........

According to the conservation of momentum law:

The total momentum of gun and bullet after the gun is fired =Total momentum of gun and bullet before the gun is fired

Therefore we get:

M V +mv = 0

or M V = -m v
