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 ...
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 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 new design is known as Scalextric Sport and can be connected to the original track using special adaptor pieces. The new track was designed to be compatible with all earlier 1:32 cars. In 2004 "Scalextric Sport Digital" (SSD) was introduced, which allows up to four digital cars to be raced in a single slot.
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 ...

T-TRAK (all letters capitalized) is a modular model railroad system based on standards for module size, track placement, track interface, and electrical connections. The standards allow for a wide range of flexibility in design yet still maintain interoperability with all modules built per the standards.
A typical chain lift consists of a heavy piece of metal called a chain dog, which is mounted onto the underside of one of the cars which make up the train. This is in place to line up with the chain on the lift hill. The chain travels through a steel trough, and is normally powered by one or more motors which are positioned under the lift hill.
