Conservation of Momentum

How is it possible for a 0.06 kg tennis ball to have more momentum than a 0.45 kg soccer ball?

• The tennis ball has a smaller mass

• The soccer ball moves in the opposite direction

• It is not possible for the tennis ball to have more momentum

• The tennis ball has more velocity than the soccer ball

According to the Law of Conservation of Momentum, when two objects collide:

• both objects lose momentum.

• both objects gain momentum

• momentum is neither lost nor gained.

• momentum is always lost or gainer.

Two soccer balls collide. The first soccer ball hits the second soccer ball which was at rest on the ground. What is true of the momentum?

• The total momentum of the isolated system stays the same.

• The total momentum of the isolated system decreases.

• The total momentum of the isolated system increases.

• The total momentum of the isolated system equals zero since the second soccer ball was at rest.

Due to the difficulty of stopping an oil tanker, the engines are cut off around 25 km from port. Why are these oil tankers difficult to stop?

• The oil tanker has a huge mass which results in an enormous momentum. The vessel needs a long distance to decrease its velocity.

• The oil tanker has a small mass which results in an enormous momentum. The vessel needs a long distance to decrease its velocity.

• The oil tanker has a huge mass which results in a small momentum. The vessel needs a long distance to decrease its velocity.

• The oil tanker has a huge mass which results in an enormous momentum. The vessel needs a long distance to increase its velocity.
