... Properties of Footwear Friction is a force. This force is when one surface slides and rubs across another and this causes friction and this tries to stop the movement of the two surfaces moving. Friction opposes the movement of an object this is noticeable when a ball is moving through the air and the air resistance is slowing the ball down until it eventually comes to a halt. This type of friction is called Kinetic (which means moving) energy into heat. Examples of Friction Running - especially when you start running pushing your feet against the ground is causing friction so that you can move forwards. Sprinter Runners have to wear spikes on the bottom of their shoes so that they can improve their grip on the running track. Football - Studs are used on football boots and this is used to improve grip when running round a pitch especially when turning. Rugby
