A large moving ball collides with a small stationary ball. The momentum

• of the large ball decreases, and the momentum of the small ball increases.

• of the small ball decreases, and the momentum of the large ball increases.

• of the large ball decreases, and the momentum of the small ball decreases.

• does not change for either ball.
