Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength, size, and temperature increase, which were done in the preliminary testing. The prototype road and car were then constructed based on the specifications that had been identified after the preliminary testing. The prototype car’s magnets were permanent magnets while the road magnets were electromagnets. They had been oriented so that the magnets would repel each other. | Investigatory Project in Physics Balloon Powered Car When it comes to powering a race car, there are a ton of different options. Some cars are powered by gasoline, diesel, or other combustible fuels, or you can even power miniature race cars using a mousetrap! In the Balloon Powered Car, we’ll show you how to build a racer that uses the power of air pressure to roll across a room. Objectives: a.) to create a balloon powered race car for maximum speed and distance b.) to incorporate Newton’s Laws of Motion Materials: * Foam core or corrugated cardboard * Wooden barbeque skewers * Regular cardboard * Straws * Tape * Balloons * Scissors * Wire cutters Procedure: 1.) Start off by cutting the chassis of your car. We don’t condone the use of blow torches or saws during Sick Science experiments, so you have to create the chassis using scissors and foam core (corrugated cardboard works great, too). Cut a 6Ãâ€"3 inch piece of your chosen material using the scissors. 2.) A car is nothing without axles. Given the size of your car, wooden barbeque skewers will make perfect axles. Use wire cutters to snip two 4†³ pieces of skewer. 3.) You need to mount the axles to your chassis in a way that allows the axles to turn freely. For mounts, cut two 3†³ sections of straw and use tape to fix the mounts to the front and back (3†³ sides) of your chassis. 4.) Now that you have axle mounts, mount your axles! Slide the wooden skewers through the middle of the straws. 5.) Axles are great, but humans invented the wheel for a reason. The wheel was invented for use on the Balloon Powered Car! Use scissors to cut four quarter-sized pieces of regular cardboard. If it helps, you can trace a quarter or circle of similar size to give yourself some guidelines. 6.) Push the cardboard circles onto the skewers, one on each end of both skewers†¦.
