All things are having roughness on that faces.Two parts are moving at touched position.That time two parts roughness is making friction with vibrate are sound.
'Gravictism'? (Formed from Gravity, Friction and Magnetism)
friction
heat and friction.
No, heat is formed by friction or burning the elements.
The friction ridges in your fingers are called fingerprints. These unique patterns are formed during fetal development and remain the same throughout your life.
Ripples are formed by a friction of moving air and water.
Absolutely! The determination of any kind of friction, kinetic friction (what you call sliding friction, once an object is in motion) OR static friction (the friction it takes to start motion) is determined by the type of materials used. It really depends on the temporary molecular bonds formed between the molecules of the material. The more bonds can form, the less easily something will move (thus the more friction it has)
tube light us formed by sum inerts gasses like neon because they do not react with electron and the friction between electron and neon produced light.
A blackhole is formed in our universe when matter falls onto the black hole and that forms an accretion disk that is heated by friction. The black hole does not allow anything to escape it.
Heat energy is formed due to Friction.
When two surfaces rub against each other, friction is formed. It is the force resisting the relative motion between fluid layers, solid surfaces and material elements that are sliding against each other.
Walking is an example of friction. when friction is formed you may slow down, but you may have a weak balance and fall to your height. friction can be used in many places, like themeparks and ice skating and even on the sole of your shoes.
