##### Some conceptual questions on momentum.

This Flipping Physics video stars Mr. P's daughters.

1. What is the momentum of an object that is not moving?
2. What is the symbol for momentum? [This is the letter used to stand for momentum in formulas.]
3. What is the SI unit for momentum?
4. Other SI units tend to have special names, like Newton's for force, Joules for energy, and Watts for power. But does momentum have a special name?
