Friction between two flat surfaces can be reduced by

Asked by admin @ 13/08/2021 in Science viewed by 309 People

choose the correct answer: Friction between two flat surfaces can be reduced by- a) Greasing,b) painting,c)using ball bearing ,d) decreasing area

Answered by admin @ 13/08/2021

Answer:

Using ball bearing

Explanation:

Due to the ball bearings, rolling friiction comes into effect. By using grease sliding friction comes into effect. Rolling friction is lesse than sliding friction. So using ball bearings have the less friction
