Linear momentum

What is linear momentum?

Linear momentum is the product of the mass and velocity of an object, represented by the formula p = mv.

What are the units of linear momentum?

The units of linear momentum are kilogram meter per second (kg·m/s).

What is the principle of conservation of linear momentum?

The principle states that the total linear momentum of a closed system remains constant if no external forces act on it.

How is linear momentum calculated for a system of particles?

The total linear momentum for a system is the vector sum of the individual momenta, p_total = p_1 + p_2 + ... + p_n.

What is an elastic collision?

An elastic collision is one in which both momentum and kinetic energy are conserved.

What is an inelastic collision?

An inelastic collision is one in which momentum is conserved, but kinetic energy is not conserved.

How does dispersion of momentum occur in collisions?

Dispersion occurs when two objects collide, transferring momentum from one to another, causing the objects to move in different directions.

Can momentum be transferred?

Yes, momentum can be transferred from one object to another during collisions or interactions.

What is impulse?

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as impulse = force × time.

How does impulse relate to momentum?

Impulse is equal to the change in momentum, expressed as Δp = FΔt.
