how friction helps moving bodies on different surfaces
Friction can slow down or speed up a moving object. Friction acts at right angles to the direction of motion. Friction can be reduced by lubricating the surface between the two moving objects. Bearings can be used to reduce friction between two moving surfaces.
even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience the same frictional force when you drag them over the ground.
