The total momentum of any group of objects remains the same unless outside forces act on the objects.

• True

• False

If outside forces such as friction are negligible, when two

objects of the same mass collide and do not stick together, the objects multiply velocities.

• True

• False

• True

• False

The less momentum an object has, the easier it is to stop.

• True

• False

Momentum, like velocity, is described by both a direction and a force.

• True

• False
