I'm not entirely positive on my understanding of this or if my explanation will make sense (because it takes a little bit of a physics background), but here goes:
Friction is a resisting force. Force= mass x acceleration. Now, heat is a type of energy that usually gets released when one type of energy becomes another type. In the physics of motion, the two main types of energy are potential and kinetic. Potential is usually due to position and kinetic is due to motion.
Since the total energy is conserved when there's a transformation of energy, the amount of potential energy (U sub i) and the amount of kinetic energy (K sub i) before the transformation is the same as the amount of potential energy (U sub f) and kinetic energy (K sub f) after the transformation.
Acceleration is the derivative of velocity, both being vectors related to rates of change in position or the rate of the rate of change in position, in the case of acceleration. Kinetic energy has to do with velocity so I imagine the fact that friction is a force (meaning it has an acceleration, meaning it has a velocity) means that there's a transformation in energy and, when that transformation occurs, heat is given off.
Does that make sense?
Essentially, friction causes potential energy to become kinetic energy and this transformation gives off heat, not unlike when energy in a chemical equation needs to balance out so heat is either absorbed or given off.
When two bodies rub together, the force called friction resists their moving over one another.
The overcoming of this force means that work is done, and the doing of work is always accompanied by heat.
When two surfaces are in contact cold welds are formed between them.
To break these cold welds force is applied. If we take it as input, it is a rule of physics that output is less then input (efficiency). So some of the force is used to produce heat, due to friction.

How do you store Kinetic Energy or use it to power something?Say I wanted to hook a manual treadmill up to a lightbulb or even a little more adventurous a TV, would it be possible to power it? also is it easily financed and available to the average person? On another tangent, how would you go about...

My daughter has driven me nuts with this all night, it's homework. I can't complete the list of 20 examples. I'm stoopid Oh and not that she is but her teacher teaches by rote. The kids don't get to explore or discover. They just get these 'go find me' lists.In advance of anyone helping thank you

What is the resistance to liquid ?As Resistance is to Electric current, Noise is to waves and friction is to Motion, What is it that causes liquid to stop after sometimes, when moving in straight pipe? If it is 'Viscosity'... will 'helium', the superfluid keep boosting its speed once accelerated in...

What are the properties of a surface that eliminates the kinetic energy of anything it touches?Basically, what would happen if I tried to punch such a surface? If air molecules came into contact with it? What if I just touched it?

My husband and I had a debate about global warming. He thinks we should spew out sulphur dioxide to cool the earth (as in the case of pinatubo) He claims a source said that in 6 months the problem will be over.But acid rain is caused by sulphur dioxide and it will poison our potable waters. I say...
