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 ...
A gravity railroad (American English) or gravity railway (British English) is a railroad on a slope that allows cars carrying minerals or passengers to coast down the slope by the force of gravity alone. The speed of the cars is controlled by a braking mechanism on one or more cars on the train. The cars are then hauled back up the slope using ...
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 ...
A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. [1] The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track. The forces experienced by the rider are constantly changing ...
The plastic track had two such lanes, and cars could change lanes with the flick of a switch on the controller. TCR sets came with "jam cars", a slow moving drone which both racers had to avoid crashing into. Like Matchbox's Powertrack, some cars featured lights. The first sets consisted of up to 4 Formula 5000 cars. The track (which stayed the ...

The 1885 patent states the invention relates to the gravity double track switchback railway, which had predicated the inclined plane railway, patented in 1878 by Richard Knudsen. [ 1 ] [ 2 ] [ 3 ] Coney Island's version was designed by LaMarcus Adna Thompson in 1881 and constructed in 1884. [ 4 ]
