Question

law of conservation of momentum states that in the obsence of a net external force on the system ________,of the system unchanged​

Answer 1

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.

Let the two bodies remain in contact with each other for a small interval "delta t".

Let F12 be the average force exerted by mass m1 on m2, and let F21 be the force on m2 due to m1.

Let v1 and v2 be the velcoities of two bodies after collision.

Momentum of mass m1 before collision=m1u1

Momentum of mass m2 after collision=m2u2

Momentum of mass m1 after collision=m1v1

Answer 2

Answer:

The answer is momentum.

Explanation:

According to the law of conservation of momentum, The overall momentum of two or more bodies acting on one another in an isolated system stays constant unless an external force is introduced.

As a result, momentum cannot be gained or lost.

According to Newton's third law, when an object A produces a force on another object B, object B responds by exerting a force that is equal in size but directed in the opposite direction.

Newton derived the law of conservation of momentum using this concept.

Examples of law of conservation of momentum:

• Blown-up balloons

• bullet and gun system

• Rocket movement
