Momentum

Which of the following, moving at the same speed, would be hardest to stop?

Which formula is used to calculate momentum?

Which moving object, in all likelihood, will have the greatest momentum?

In which situation does the law of conservation of momentum apply?

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

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.

Newton's "quantity of motion" is conservation.

Newton defined momentum as "quantity of motion."

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

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