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 ...
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 ...
GRACE uses precise measurements of the motions of two spacecraft in Earth's orbit to track the movement of water through the oceans, land, and atmosphere. Change in mass of the Greenland and Antarctic ice sheets as measured by GRACE. GRACE also detects changes in the gravity field due to geophysical processes.
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 ...

Motorific is the brand name of a line of battery-operated slot car toys and related accessories marketed by the Ideal Toy Company from 1964 to the early 1970s. It differed from traditional slot car sets in that the cars were powered independently by a pair of AA batteries, rather than by an electrical connection to the track.
The model car "kit" hobby began in the post World War II era with Ace and Berkeley wooden model cars. Revell pioneered the plastic model car in the late 1940s with their Maxwell kit, which was basically an unassembled version of a pull toy. Derek Brand, from England, pioneered the first real plastic kit, a 1932 Ford Roadster for Revell.
