When I was in Jacksonville I went to a go kart place called the Autobahn Indoor Speedway. These weren't your typical go karts however. At the Autobahn the cars reached speeds up to 50 mph! Drivers have to wear helmets for safety and the speed made for some pretty intense races. There was a lot of physics involved in driving the cars. One of the most important parts of learning how to be as fast as possible was getting used to knowing how much and when to brake around turns. Braking too much will slow you down and can cause wrecks, however not braking enough can cause you to slam your car into the wall, also slowing you down and putting you at risk of wrecks. The only way to do this was through friction. By stopping the rotation of the wheels the tires then grinded against the concrete ground creating friction which is what would slow down your car. Also many forces were exerted with the bumping of cars and from running into walls. If my car ever rammed into another, the force exerted from my car onto his was the same amount of force his exerted onto mine. A lot of centripetal acceleration also takes place at all 4 of my wheels. Even if my car is moving at a constant velocity, the wheels are constantly changing direction as they spin and therefore accelerating inward. Finally the force of gravity is always constant on me and my car. Gravity exerts a force of 9.81 m/s^2, which is what keeps me and my car from flying off of the track. The Autobahn Indoor Speedway was a pretty intense go karting place and I had a lot of fun racing!
