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 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 images and spectra of Europa, published in the Planetary Science Journal, reveal that Europa’s crust is mainly composed of frozen water ice with non-ice materials contaminating the surface.

This model represents the "far-field" gravitational acceleration associated with a massive body. When the dimensions of a body are not trivial compared to the distances of interest, the principle of superposition can be used for differential masses for an assumed density distribution throughout the body in order to get a more detailed model of ...
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 ...
