In an atmosphere, when an object moves through the air it experiences friction with the air through which it moves. In a vacuum, there is no air and therefore no friction with an atmosphere as the result of an object moving through space.
However, if two surfaces are moving against each other, there would still be friction from that action, even in a vacuum. In fact, in the absence of air that kind of friction could be increased.
Objects with smooth surfaces or lubrication between them tend to have less friction. In a vacuum or in microgravity environments, there is also less friction between objects.
Yes, in general friction can occur in a vacuum, but the only kind of friction that doesn't occur in a vacuum is, of course, air friction. There is no drag force on an object falling in a vacuum.
no
less friction then what?
no limiting friction is not less than rolling friction
rolling friction is 1/100 less than spliding friction
No, We cannot do work on friction less surface
TIs is
No, there is not.
No.
An ice cube has less friction than a sponge
than what?
