Grady from Practical Engineering compares the physics of pulling road vehicles versus railcars, revealing why rail transport ...

1 The maglev cars developed by OIST differ significantly ... this technology is the near-complete elimination of friction, a major cause of energy loss in traditional vehicles.

Less friction means more efficient movement as less energy is lost to friction forces. This means that the shape of the car allows air to flow over the surface of the car more easily. This reduces ...

When friction acts between two surfaces that are moving over each other, some kinetic energy is transformed into ... and the friction between a car tyre and the road surface helps cars to speed ...
