it is when friction occurs when moving parts have ball bearings.
Yes, since friction is independent of gravity.
You need high friction so your feet and hands don't slip.
No. Either the inner, or outer, at least one race, has to be a press fit, otherwise it is no longer a bearing that is needed. A bushing would work. With both races turning you eliminate the bearing.
ores
By virtue that a meteor is a meteoroid that is burning up in the Earths atmosphere due to friction, then the answer is yes.
A friction bearing is a solid bearing that directly supports the end of an axle. Friction is when the bearing and the joint are running together.
anti-friction bearing
in friction type the bearing metal is direct contact with shaft metal, but in the antifiction the rolling element is contact with the bearing races only.
what are the example sof antifriction bearing
The definition of sliding friction is the force that prevents a sliding object from moving.

the difference between frriction bearing and antifriction bearing kya jan ke karega maal pata dateing ja or as kar......... bye...........
static friction,limiting frictionand kinetic friction
A shaft bearing is a low friction support device for a rotating member of a mechanical machine.
contact
In case of rolling contact bearings there is either point contact or line contact between rolling elements and races of the bearing depending on whether it is ball bearing or roller bearing... In case of plain or journal bearings contact is generally area contact. Hence friction is reduced in rolling bearing as compared to a plain bearings.
Fluid Friction is friction created by a fluid or gass, and sliding friction practical says it in the name stupid
