The numerical model was validated by comparing the temperatures recorded at a subset of locations with those recorded at the … WebExplain Effects of Friction on Motion. Friction has an enormous influence on the motion of an object. Friction is a kind of resistive force which slows down the motion of a body. It can be defined as the force that resists the relative motion of solid surfaces, fluids, or elements that collide or slide against each other. se flow
