the ground and gravity level has the catipillar friction
Rolling Friction
when the centripetal force is greater than frictional force,skidding occurs.if mu is the coefficient of friction between the road and tyre,then the limiting friction .
Friction is called friction because it originates from Latin to mean Heat.
It then presume the friction is very small and presume no friction. In fluid and piping, it mean any pressure drop term is due to fluid motion and dispersion alone.

because its changing the speed and direction
Friction. Oonce the train is clear of the track, there is no friction to slow it down.
I'm not too sure about the advanced physics of this, but I know that it is desired for Maglev trains to not touch the track so that their speed can be maximised, and so there is no wear and tear of the track and contact. The speed would be maximised because if you don't touch the track there is no friction. Even wheels are slowed by friction so the only way to completely eliminate it is to have no friction.
The track and tires are both sprayed with a special solvent compound.
track. anything that has to do with running. you use friction when running. but as for the 5 without use of friction then i have no idea
Friction

Friction and Gravitational forces
Think about it as a toy car on a wooden track. The more the car weighs, the more friction between the car and track. Therefore, reducing speed(b/c of friction). Hope this helps!
In that case, the centripetal acceleration - and therefore also the static friction - will increase by a factor of 4.
