NettetWood must be raised to a temperature of about 250 °C (about 480 °F) for a spark or flame to ignite it, but at a temperature of about 500 °C (about 930 °F) ignition is spontaneous. The flammability of wood can be reduced by chemical treatment (see the … NettetOnce the applied force exceeds f s (max), the object will move. Once an object is moving, the magnitude of kinetic friction fk is given by f k = μ k N. where μ k is the coefficient of kinetic friction. Friction varies from surface to surface because different substances are rougher than others.
