Định Nghĩa và Ý Nghĩa của "slot car"

What is a "slot car"?

A slot car is a small, electrically powered toy car that runs on a track with narrow grooves or "slots." The car has a guide pin or blade that fits into the slot, which keeps it aligned as it moves along the track. Slot cars are controlled by a hand-held controller that regulates the speed of the car by controlling the flow of electricity. These cars are often used in racing games, where players compete to see who can drive their car the fastest around the track. Slot cars help develop coordination and understanding of speed and control in a fun, competitive way.
