How is momentum conserved when the big rolling ball hits the smaller rolling ball?
Responses
Momentum is not conserved when the two balls collide.
Momentum is not conserved when the two balls collide.
The small ball had no momentum before the collision, and afterward it has all the momentum.
The small ball had no momentum before the collision, and afterward it has all the momentum.
The big ball gives all of its momentum to the small ball.
The big ball gives all of its momentum to the small ball.
The big ball transfers some of its momentum to the small ball, but it keeps going forward, too.
The correct response is:
The big ball transfers some of its momentum to the small ball, but it keeps going forward, too.
