How fast can a CO2 car go?
They’re super quick, on a (20-metre) track, the cars can cross the finish line in just over a second, travelling at a top speed of around 90 kilometers per hour. The CO2 dragster may be small, but it’s going to be moving at incredible speeds when you race it.
How do you make a CO2 car go faster?
Simply put, the less weight your dragster has, the faster it will go. This is the most important factor that will figure into your design. Keep it light! Thrust: The gas escaping from the CO2 cartridge in the car.
What is the fastest CO2 car?
The recent Braden River High graduate built the fastest CO2 dragster in the nation, racing his way to a first-place finish in the Technology Student Association’s national dragster competition and setting a national record of . 925 seconds on a 65-foot track.
What is the most aerodynamic CO2 car?
Shell cars
Shell cars are bullet-shaped, hollowed-out bodies with the wheels enclosed inside. These are definitely the most aerodynamic of any design, and will usually come to dominate any class into which they are allowed.
How do CO2 cars perform races?
CO2 dragsters are cars used by miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a 20 metre track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, or aerodynamics.
How do CO2 cars operate?
CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. The cartridge is positioned in the car so that the escaping gas moves rearward. The rearward force of the escaping gas is the initial action described by Newton. The reaction part of Newton’s law is fulfilled by the car’s movement.
How can I make my CO2 car more aerodynamic?
Three Things You Can Do to Reduce Drag in CO2 Cars
- Golf Balling. Covering the surface of your car with small, semi-circular pits (“golf balling”) does two things.
- Get Low. The bottom of your car experiences just as much drag as the top, so make sure to keep things smooth and straight all the way around.
- Sleek Over Small.
What are CO2 cars used for?
CO2 dragsters are cars used as miniature racing cars which are propelled by a carbon dioxide cartridge, pierced to start the release of the gas, and which race on a typically 60 feet (18 metres) track. They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, and aerodynamics.
How are CO2 cars powered?
CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. The cartridge is positioned in the car so that the escaping gas moves rearward. The rearward force of the escaping gas is the initial action described by Newton.
What role do the shape of the race car track play in the race car motion?
NASCAR tracks use banked turns that are sloped to keep race cars tilted inwards. The race cars, which can reach speeds faster than 200 mph, would fling outwards and off the track if not for the banked turns.
