Answer:
It actually depends. 
If person A bumps person B, it is most likely that person B will fall due to the fact that it is unexpected. Person B hasn't prepared her/his body for the impact so person B will fall.
If person A and person B both run and bump each other, both of them will fall due to the impact.
I hope this helped!
Have a great day:)
