Question

How do the use of wheel and ball bearing reduces friction? PS: don't search it in Google and it's urgent so be true​

Answer 1

Don't no friend only ik this one

Bearings reduce friction by means of a rolling motion

Figure 1 shows how the "shaft" rotates, causing the rolling elements ("balls" or "rollers") inside the bearing to roll. Bearings reduce friction by means of this rolling motion

Answer 2

Bearings reduce friction by means of this rolling motion. The "rolling bearing", with its rolling motion, reduces friction more than the "plain bearing" with its sliding motion, allowing for a greater decrease in the amount of energy consumption during rotation.
