Friction. Causes of Friction. Friction is a force resisting motion of an object when in contact with another. This resistive force is caused by the surface roughness of the contact area of the materials, molecular attraction or adhesion between materials, and deformations in the materials.
The friction is acting opposite to the ball rolling in the ground. Friction is a force that resists motion. It always acts in the opposite direction to the motion. Friction is caused by bumps on the two surfaces(whic are in contact), rubbing as they slide across each other. Friction means that objects slow down and lose kinetic energy.
