its because of lubrication
Friction causes kinetic energy to be converted into heat energy.
Friction causes mechanical energy to be transformed into heat energy.
where is friction used in wrestling
Friction is not useful when ever we do not want it. Examples would be when two materials are rubbing against one another. The friction of ropes in pulleys eventually causes wear on both; friction of shoes or straps against the body causes blisters; friction airplanes travelling through the air - friction causes the plane to get hot; the moving parts of an engine get hot from friction...
There is no friction IN static electricity. However static electricity can be caused BY friction.
Friction is a force present when things rub against eachother. Friction causes heat energy, and it also causes motion between surfaces to be reduced.
The Elephant Vanishes was created in 1993.
Friction
Friction causes wear and tear.
when we run we push the ground backward it causes friction
Absolutely nothing could make any purposeful movement and nothing would stay-put if any force were applied to it.
