| − | + | Ever wonder why your hands get warm when you rub them together quickly or why rubbing two sticks together can eventually start a fire? The answer is friction! When two surfaces rub against each other, they naturally resist each others' movement at a microscopic level. This resistance can cause the release of energy in the form of heat, warming your hands, sparking a fire, and so on.<ref name="rf1">http://www.livescience.com/37161-what-is-friction.html</ref> The greater the friction, the more energy released, so knowing how to increase the friction between moving parts in a mechanical system can potentially allow you to generate lots of heat! | |
