When friction is created by two objects that are moving but not relative to each other, its called static friction. Static friction keeps an object from moving until friction is created to move it.
friction
they reduse the friction between the machine parts.
Lubrication is the use of oil and grease to increase friction in a vehicle's moving parts
yes
it is when friction occurs when moving parts have ball bearings.
it is a mechanical equipment to reduce friction. It is used in moving parts very often.
Ball bearings use tiny balls to maintain separation between moving parts of a load bearer. They are effective because they are very cheap to make, and the rolling balls reduce friction between the moving parts of the bearing.

Machine parts use ball bearings to reduce friction, making it easier to move the moving parts and producing less wear on the parts.
To prevent metal on metal contact. Friction is the destroyer of all moving parts,they must always be lubricated.
The bearings don't need friction, but everything else does. It there wasn't any friction it'd be impossible to bolt anything together.
in machineare parts
friction
They are the parts of the hub which touch the stub axle. They are made a friction-free as possible and in modern cars are roller bearings or ball bearings.
Moving parts in a machine.
Parts of car that needs friction are many , some of them are listed below: 1. car and road-tires . 2. In different parts of car engine e.g: Cam lobes, cam followers, lifters, cam bearings, main bearings, rod bearings, cylinders and piston rings, cylinders and piston skirts.
