What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

How does the velocity of an object affect its momentum?

Back

The momentum of an object increases with an increase in its velocity, as momentum is directly proportional to velocity.

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved, while in inelastic collisions, momentum is conserved but kinetic energy is not.

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as the product of the force and the time duration.

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object, expressed as Impulse = Δp = FΔt, where Δp is the change in momentum, F is the force, and Δt is the time duration.

What factors affect the momentum of an object?

Back

The momentum of an object is affected by its mass and velocity; increasing either will increase momentum.

What happens to momentum in a closed system during a collision?

Back

In a closed system, the total momentum before the collision is equal to the total momentum after the collision, according to the law of conservation of momentum.
