Question

Ball bearings reduce friction because they .................rather than slide

Answer 1

Answer:

Ball bearing reduce friction because theyroll rather than slide

Explanation:

Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races.

Answer 2

Because they roll rather than slide.
