Conservation of Momentum

Front

What is the equation for momentum?

Back

Front

What word can best describe the total momentum in an isolated system?

Back

Constant.

Front

In a perfectly inelastic collision, what happens to the objects involved?

Back

The objects stick together after colliding.

Front

What does the Law of Conservation of Momentum state?

Back

The total momentum before a collision is equal to the total momentum after a collision.

Front

Is momentum conserved when two carts collide and stick together?

Back

Yes.

Front

Define momentum in physics.

Front

What is an isolated system in the context of momentum?

Back

An isolated system is one where no external forces act on the objects within it, allowing momentum to be conserved.

Front

What is the difference between elastic and inelastic collisions?

Back

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

Front

What is the formula for calculating the total momentum of a system of objects?

Back

Front

What happens to kinetic energy in a perfectly inelastic collision?

Back

Kinetic energy is not conserved; some of it is transformed into other forms of energy, such as heat or sound.
