Europa's gravity is approximately 13% of Earth's. The temperature on Europa varies from −160 °C at the equator, to −220 °C at either of its poles. [145] Europa's subsurface ocean is thought to be significantly [clarification needed] warmer however. It is hypothesized that because of radioactive and tidal heating (as mentioned in the ...
As the car approaches a loop, the direction of a passenger's inertial velocity points straight ahead at the same angle as the track leading up to the loop. As the car enters the loop, the track guides the car up, moving the passenger up as well. This change in direction creates a feeling of extra gravity as the passenger is pushed down into the ...
A 242A1 locomotive and standard gauge track at some model railway scales. This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA.
The clockwork or battery-operated cars had a guide wheel on the underside that set within coiled wire tracks. The tracks could be arranged in various configurations of the owner's own design. Different plastic pieces could be linked with the wire track to create intersections and overpasses.
Model car, for use on a toy racing track Slot car, a powered miniature auto or other vehicle that is guided by a groove or slot in the track on which it runs; Safety car or pace car, a car which limits the speed of competing vehicles on a racetrack during caution period or parade lap; Track day car, a road car designed solely or principally for ...

Europa Clipper is designed to follow up on evidence for a subsurface ocean underneath Europa's ice crust, found using the Galileo spacecraft which orbited Jupiter from 1995 to 2003. Plans to send a spacecraft to Europa were initially conceived with projects such as Europa Orbiter and Jupiter Icy Moons Orbiter , in which a spacecraft would be ...
F1 in Schools Competition Track. STEM Racing (formerly F1 in Schools) is an international STEM competition endorsed by Formula 1 for students aged 9–19. Groups of 3–6 students have to design and manufacture a miniature F1 car using CAD/CAM and CAE design tools. The cars are powered by CO 2 cartridges and are attached to a track by a nylon ...
