momentum

Front

What is the law 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

Define momentum.

Back

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

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg*m/s).

Front

How do you calculate momentum?

Back

Momentum (p) is calculated using the formula p = mass (m) × velocity (v).

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

If two objects collide and stick together, what type of collision is it?

Back

It is called a perfectly inelastic collision.

Front

What is the relationship between mass and momentum?

Back

For a constant velocity, an increase in mass results in an increase in momentum.

Front

What is the relationship between velocity and momentum?

Back

For a constant mass, an increase in velocity results in an increase in momentum.

Front

If an object is at rest, what is its momentum?

Back

The momentum of an object at rest is zero.
