An F1inSchools car is a 1:30 scale F1 car powered by a CO2 cartridge, which causes the car to accelerate when it releases its compressed carbon dioxide. This phenomenon is due to the principle of the conservation of momentum. Right after the cartridge is emptied, the car starts decelerating because forces opposite to the direction of its motion are exerted on it (drag, friction etc.). The goal is to reduce such forces as much as possible in order to make the quicker.
The F1inSchools car races across a 23.6m long straight F1inSchools track. At the start, five red lights turn on gradually – just like in F1 – and the moment they go out, the person responsible for launching the car presses the trigger of the launch mechanism, causing the start box (device placed behind the cartridge) to pierce the CO2 cartridge. Both the reaction time of the “driver” and the time that the car takes to complete the track are taken into account to determine the fastest team.
