Here's why:
* Momentum (p) is a measure of how much motion an object has. It's a vector quantity, meaning it has both magnitude (amount) and direction.
* Mass (m) is the amount of matter in an object.
* Velocity (v) is the rate of change of an object's position over time, including both speed and direction.
The formula for momentum is:
p = m * v
This means that an object with more mass or moving at a higher velocity will have a greater momentum.
