Answer:
Explanation:
1) Friction is a force between two surfaces that are sliding, or trying to slide, across each other
2)Friction always slows a moving object down.
3) The amount of friction depends on the materials from which the two surfaces are made.
4) The rougher the surface, the more friction is produced.
5) It is not a fundamental force, like gravity.
6) When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat).
7) Friction is desirable and important in supplying traction to facilitate motion on land.
8) Friction can be increased by roughing the surface for example
treads on car tires and number of gears in the motors etc.
9) Friction can be reduced by decreasing the amount of roughness by smoothing it for example
by applying grease or fluids or by using ball bearings in heavy machines
10) Friction is the most important factor we are born and we live our lives normally and comfortably
hope it helps !!
