Answer the following question given this paragraph: 

This equation shows that momentum is directly related to both mass and velocity. An object has greater momentum if it has greater mass, greater velocity, or both. For example, a bowling ball has greater momentum than a softball when both are moving at the same velocity because the bowling ball has greater mass. However, a softball moving at a very high velocity — say, 100 miles an hour — would have greater momentum than a slow-rolling bowling ball. If an object isn’t moving at all, it has no momentum. That’s because its velocity is zero, and zero times anything is zero.


Q: Momentum is directly related to both mass and?


A:
velocity
