2. The definition of momentum is "mass in motion." Since every item has mass, if it is moving, it must have momentum because its mass is in motion.
3. The amount of motion and the speed of the motion are the two factors that determine how much momentum an item possesses.
4. The factors mass and velocity affect momentum. An object's momentum can be calculated mathematically by multiplying its mass by its velocity.
5. The SI unit of momentum is kg m/s.
