Momentum Review

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 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 inelastic collision?

Back

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

Front

What is an elastic collision?

Back

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

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 x Time.

Front

How does mass affect momentum?

Back

Momentum increases with mass; for a given velocity, a heavier object has more momentum.

Front

What is the relationship between force and momentum?

Back

The force applied to an object is equal to the rate of change of its momentum (F = dp/dt).

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

In a collision, which object experiences a greater change in momentum?

Back

In any collision, the change in momentum is equal for both objects involved.

Front

What is the impulse-momentum theorem?

Back

The impulse-momentum theorem states that the impulse on an object is equal to the change in momentum it causes.
