Question

a moving ball rolls into a stationary ball. the total momentum of both balls after the collision will be

Answer 1

The moving ball exerts a force on the stationary ball.

The stationary ball exerts a force on the moving ball.

When two objects collide, each object exerts a force on the other. Unlike energy, force can’t be transferred between objects. Force has strength and direction, but it isn’t a property of an object.

Answer 2

the momentum of the rolling ball will have less momentum than before the collision and the stationary ball will have more momentum after the collusion.
