The factors that will increase momentum of a rolling ball are:
A. Moving from a flat surface to moving downhill.
C. A moving object traveling in the same direction as the ball colliding with it.
Factors that increase momentum:
The gravitational power of the Earth ready makes the ball speed up, and in this manner pick up speed.
If you increase either mass or velocity, the momentum of the object increases proportionally.
Thus, the factors that increase the momentum of a rolling ball are
A. Moving from a flat surface to moving downhill.
C. A moving object traveling in the same direction as the ball colliding with it.
