No there is always a resistive force such as air resistance.
The closest frictionless train is the japanese magnetic train which has no friction on the track.
Devices that allow frictionless travel have been present throughout science fiction. At current transportation using magnetism is limited to the same principles that allow Maglev Trains to function.
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
yes
slickness, smoothness, frictionless
Yes, a person can jump on a frictionless floor, but the mechanics are different from jumping on a normal surface. On a frictionless floor, the person would not be able to push off effectively, as there would be no friction to provide the necessary force against the ground. Instead, any attempt to jump would result in them sliding rather than gaining vertical height. Thus, a jump would not be successful in the traditional sense.
No a train does not float in the air, no train does.
Everywhere! Frictionless surfaces do not exist.
it is the act of without friction.

Frictionless data means sharing data though social media sources. It a cheap way of sharing data and allows for massive amounts of data to be shared easily.
