How is the momentum formula derived?

Section Summary

1. Linear momentum (momentum for brevity) is defined as the product of a system’s mass multiplied by its velocity.
2. In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity.
3. The SI unit for momentum is kg · m/s.

What is the equation for Newton’s second law in terms of momentum?

Newton’s second law, in its most general form, says that the rate of a change of a particle’s momentum p is given by the force acting on the particle; i.e., F = dp/dt.

Can momentum be created?

The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton’s laws of motion.

What is conservation of momentum derive its equation?

The interaction time between two particles is denoted by the letter t. As a result, the equation of the law of conservation of momentum is as follows: m1u1+m2u2 represents the total momentum of particles A and B before the collision, and m1v1+m2v2 represents the total momentum of particles A and B after the collision.

Which of Newton’s laws says that for every action there is an equal and opposite reaction?

Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Why can’t momentum be created or destroyed?

The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton’s laws of motion. Momentum is conserved in all three physical directions at the same time.

How is the law of conservation of momentum derived?

As a result, the equation of the law of conservation of momentum is as follows: m 1 u 1 +m 2 u 2 represents the total momentum of particles A and B before the collision, and m 1 v 1 +m 2 v 2 represents the total momentum of particles A and B after the collision.
