Heat generated by friction formula
WebSuppose there are two objects: A = m1 and B = m2 . A is travelling at a constant velocity v toward B and collides inelastically: is there a way in which I could determine the energy which is dissipated as heat? What other variables I should know before it can be calculated? WebIntroduction: Friction at the Molecular Level Viscosity is, essentially, fluid friction. Like friction between moving solids, ... it is a measure of how much heat is generated when faster fluid is flowing by slower fluid, but it is also a measure of the rate of transfer of momentum from the faster stream to the slower stream.

WebAnswer: On a flat surface, the normal force on an object is η = mg. Using this, the formula can be used to find the force of friction: Ff = μη Ff = μ mg Ff = (0.400) (50.0 kg) (9.80 m/s 2) Ff = 196 kg∙m/s 2 Ff = 196 N The force due to friction acting on the boat is 196 N.
