The things will slide
less wear
No, sand does not reduce friction but increase friction.
* lubricanting like oil, greese, etc. * by using ball bearing * polishing * stream lining Water can reduce friction. Also, round things like wheels and straws can reduce friction. Things that are placed on wheels, straws, pencils, etc. can move far with a soft push.
Lubrication to reduce friction. To increase friction step on the brakes.
Reduce friction or increase slope.
yes because when they brake the friction is caused to reduce
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
No. friction produces thermal energy therefore friction produces heat. Rub your hands together and see what happens.
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
the factors that reduce in case of friction are the velocity and acceleration.
Oil is used to reduce friction.
