<span>When you are in the way of a moving object and a collision is sure to occur, you are better off decreasing its momentum over time. Which is nothing but force.
mv/t = m.a = F
Fill the blank as: "Time"

The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces
(ii) roughness of the surface
(iii) deformation of bodies.
