Momentum

Front

What is momentum?

Back

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

Front

What is the unit of momentum?

Back

The unit of momentum is kg m/s.

Front

How does mass affect momentum?

Back

The greater the mass of an object, the greater its momentum, assuming velocity is constant.

Front

How does velocity affect momentum?

Back

The greater the velocity of an object, the greater its momentum, assuming mass is constant.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision.

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 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

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object: Impulse = Δp = p_final - p_initial.

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.
