Write about an activity to show that the friction produes heat
Answers
Explanation:
Answer:When two bodies come in contact with each other friction acts between them. During friction mechanical energy is converted into heat energy. Two sticks are rubbed together to generate fire , generally it takes a long time but the sticks get hot and eventually fire is generated.
Answer:
Friction is inherently a non conservative(dissipative) force. It implies that there is a loss of energy where there is friction acting. Also it is a mechanical phenomenon (electromagnetic phenomenon actually but macroscopically it is mechanical in nature). So mostly the energy lost is manifested in the form of heat and sound(in that order). Five examples you can find commonly are:
In winter seasons rubbing your palms together produces heat from friction.
❥The tyres of fast moving vehicles get heated up due to friction.
❥Most meteors do not reach the surface of the earth. Due to their extreme velocities, they experience huge amount of friction with air causing them to melt down before reaching the surface.
❥Friction helped mankind discover fire. The same idea is applied to a gas burner in the kitchen to create a spark.
❥Friction welding is a technology used to weld two pieces of metal together. The point of joining are rubbed against each other at a high frequency causing them to melt down at that small area and then is left to cool down.
❥To summarise, you can find heat from friction everywhere. It is a characteristic property of frictional force.
