Rolling friction is ______ sliding friction.
Since rolling friction is less than sliding friction, sliding friction is replaced with rolling friction in most machines using ball bearings.
Ball bearing is a device which usually converts: (a) rolling friction into sliding friction (b) static friction into sliding friction (c) sliding friction into rolling friction (d) rolling friction into static friction
Which of the following is not used to change sliding friction into a much smaller type of rolling friction?
Is rolling friction greater than sliding friction?
What is sliding friction and rolling friction.
