Question

Give two method of reducing friction.

Answer 1

hey thr answer is ....

lubricants like oils, greece

and ball bearings.

and wheels.


hipe it helps uu dear

Answer 2

$\textbf{Make the surfaces smoother}$ Rough surfaces produce more friction and smooth surfaces reduce friction. Some swimmers wear suits to reduce underwater resistance. These suits mimic the smooth skin of sharks.

$\textbfLubrication$ is another way to make a surface smoother. A lubricant is a slippery substance designed to reduce the friction between surfaces. You might use oil to stop a door from squeaking - the oil reduces the friction in the hinge. Water can be used as a lubricant - think of how a floor becomes slippery after it has been mopped.
