WebYou know that friction produces heat. That's why rubbing your hands together makes them warmer. But do you know why? Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer. Heat from friction can be useful. It not only warms your hands. WebAnswer (1 of 4): In general, friction transforms kinetic energy to heat but not necessarily. For example if rubber is rubbed against rubber the friction doesn’t cause to much heating although that its very high.
