1. Mass (m): The amount of matter in an object. A more massive object will have more momentum than a less massive object, assuming they are moving at the same velocity.
2. Velocity (v): The speed and direction of an object's motion. A faster-moving object will have more momentum than a slower-moving object, assuming they have the same mass.
The formula for momentum is:
Momentum (p) = Mass (m) x Velocity (v)
