How do you find the heat produced from the frictional force between two objects. For example, a person roller skating on a rink or a car going at 100m/s.

i guess not
I would calculate it. (Work done to maintain that motion on that surface) - (wind resistance on that body at that speed). Practically 100% of the difference is energy being lost as heat from friction.M_of_A_v_T said:How do you find the heat produced from the frictional force between two objects.

The tyres of a car get warm/hot from travelling, even if you have not touched the brakes. The faster and more erratic you drive, the hotter they would get. To get around corners, you hope there will be plenty of friction and tyre deformation.Priya123 said:if u take a person driving a car for example only if the car has put up a brake will friction occur right? at that time heat is produced that i accept
Friction produces heat through the conversion of mechanical energy into thermal energy. When two surfaces rub against each other, the irregularities on the surfaces create resistance and slow down the motion, resulting in the generation of heat.
The amount of heat produced by friction depends on the force of the contact between the two surfaces, the speed of the rubbing motion, and the type of materials involved. Rougher surfaces and higher contact forces result in more heat production.
The heat produced by friction can be measured using a thermometer or a calorimeter. The temperature rise on the surfaces in contact can be recorded, or the amount of heat absorbed by a substance can be measured to determine the heat produced by friction.
Understanding heat produced by friction is important in various industries, such as manufacturing, transportation, and energy production. It helps in designing efficient machinery and reducing energy loss due to friction. It is also essential in developing safety measures to prevent excessive heat production and potential fire hazards.
Yes, friction can produce enough heat to cause damage. In extreme cases, the heat produced by friction can cause materials to melt, ignite, or even explode. It is crucial to understand and control friction to prevent potential damage and ensure safety.
