Front

What is momentum?

Back

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

Front

When is momentum conserved?

Back

Momentum is conserved in a closed system where no external forces are acting.

Front

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 impulse = force × time.

Front

What happens to momentum in an elastic collision?

Back

In an elastic collision, both momentum and kinetic energy are conserved.

Front

What happens to momentum in an inelastic collision?

Back

In an inelastic collision, momentum is conserved, but kinetic energy is not.

Front

What is the difference between elastic and inelastic collisions?

Back

Elastic collisions conserve both momentum and kinetic energy, while inelastic collisions conserve momentum but not kinetic energy.

Front

How does mass affect momentum?

Back

An increase in mass will increase momentum if velocity remains constant, as momentum is directly proportional to mass.

Front

How does velocity affect momentum?

Back

An increase in velocity will increase momentum if mass remains constant, as momentum is directly proportional to velocity.

Front

What is the formula for calculating momentum?

Back

The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum of an object, expressed as impulse = Δp.
