The Law of Conservation of Momentum states which of the following?
energy can't be created or destroyed
an object in motion tends to remain in motion AND an object at rests tends to remain at rest unless acted on by an unbalanced force
the total momentum before the collision must be equal to the total momentum after the collision
the greater the distance between two objects, the weaker the force of attraction between them

Why does a cannon recoil (move in the opposite direction of the cannonball) when it fires?
the cannon has more momentum than the cannonball
the cannon has less momentum than the cannonball

the cannon and cannonball have the same mass

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
Why does a cannon recoil with less velocity than the cannonball's velocity?
Because while momentum is conserved, the cannon has much more mass than the cannonball
Because while momentum is conserved, the cannonball has much more mass than the cannon
Because momentum is not conserved and the cannonball has more momentum than the cannon
None of these
