Why is friction produced?

Answer 1

The two surfaces rub together which causes the molecules in the materials to move around more, colliding with each other and causing an increase in heat produced.The breaking of bonds releases energy in the form of heat.

Answer 2

When you rub two things together causing friction you are stretching the bonds between those atoms. When you move past, those bonds now relax back to their original state and have extra energy left over which is heat.
In other words.
When atoms are moved close together they store potential energy. When they move apart the energy becomes kinetic. The kinetic energy usually isn't enough to escape the object they are attached to so the energy is randomly distributed as kinetic energy between the atoms of the object or thermal energy ( heat ).

Answer 3

Friction is produced when two surfaces rub against each other, creating resistance to movement. This resistance is due to irregularities in the surfaces, as microscopic bumps and grooves on the surfaces interlock and cause a force opposing the motion.

Answer 4

because the atoms are colliding with each other which creates friction which then increases the heat.

Answer 5

Friction of two pieces of wood causes them to heat up until they reach the combustion temperature end ignite.

Answer 6

because of the conversion of energy .....when we apply energy that energy is change into heat due to the hitting between to surface electrons....

Answer 7

The two surfacesses rub together which causes the molecules in the materials to move around more, colliding with each other and causing an increase and is heat produced.

Answer 8

Friction creates heat because it is rubbing against another object. The atoms move more and more as they are contacted. Thus movement is energy released as heat.

Answer 9

FRICTION is produced by the rubbing of one object or surface against another.

so when you rub or do something you produce friction..
