state and explain law of conservation of montum
Answers
Answer:
One of the most powerful laws in physics is the law of momentum conservation. ... For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
It states that the total momentum of any system of objects remains constant in the absence of any external force. According to the law of conservation of momentum, for a collision between two bodies.
Total momentum before collision = Total momentum after the collision.
m1u1 +m2u2 = m1v1 m2v2
Example: When a shot is fired from a gun, the gun recoils. When the shot is fired, it leaves the barrel with a certain force. The outgoing shot causes a reaction on the gun. Thus an equal and opposite force acts on the gun and it recoils
