WebJan 4, 2024 · The effect is due to the friction force that the floor exerts on the box causing it to decelerate (slow down) losing kinetic energy and generating heat. From Newton’s third law the friction force on the box due to the floor is equal and opposite of the friction force on the floor due to the box. However, from Newton’s second law, a = F m. WebMar 15, 2024 · The dependence or independence of friction on contact area. Answered. The attempt to compare static friction (non dissipative) and rolling resistance (dissipative). Answered. As far as heat goes, technically friction does not generate heat. Friction increases the internal thermal energy and temperature of materials by means of work … WebSolution. Verified by Toppr. Correct option is C) Friction is produced due to the irregularities between surfaces. Thus, when these surfaces rub against each other they produce heat.
