Investigatory Project in Physics Submitted by Jay Loteyro Anecito Trongcoso Submitted to Ms. Matilde Macawile pilot powered elevator cable railroad 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 yet power miniature race cars using a mo occasiontrap In the balloon ply Car, well show you how to build a racer that uses the power of denudate pinch to roll across a room. Objectives a. ) to create a balloon powered race car for maximum speed and distance b. ) to incorporate Newtons rights of exertion Materials Foam core or corrugated cardboard * Wooden cook emerge skewers * Regular cardboard * Straws * Tape * Balloons * Scissors * Wire cutters Procedure 1. ) fetch off by cutting the strain of your car. We dont condone the use of whiff torches or saws during Sick Science experiments, so you have to create the chassis using scissors and foam core (corrugated c ardboard works great, too). extirpation a 63 inch piece of your chosen worldly using the scissors. 2. ) A car is nothing without axles. Given the size of your car, woody barbeque skewers will make perfect axles. Use wire cutters to range two 4 pieces of skewer. 3. You need to patronage the axles to your chassis in a way that let ins the axles to turn freely. For mounts, cut two 3 sections of straw and use enter to fix the mounts to the front and back (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 macrocosm 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. akin essay Vinegar Battery ConclusionIf it helps, you can trace a quarter or circle of similar size to give yourself about guidelines. . ) Push the cardboard circles onto the skewers, one on each ki bosh of twain skewers. Without needing lug nuts or a compression wrench, youve mounted your wheels. 7. ) flash back the mouth ring (the lip that you swagger into) off of the balloon. This will allow for a better seal between the balloon and the swallow shout out. 8. ) For the exhaust pipe, insert a straw approximately 1 into the balloon. Use tape to securely fasten the straw inside the balloon. The tighter the seal, the better your exhaust pipe is going to work, so make sure as little air as possible can escape. 9. Mount the exhaust pipe so that the point where the straw and balloon connect is about 1 from the end of your chassis. Taping it at this point is your best bet. Secure the straw so that it points straight out from the chassis. 10. ) Inflate the balloon and pinch the straw to progress air inside the balloon. Place the racer on the ground and let it go Conclusion The concept behind the Balloon Powered Car is pretty simple, but that doesnt make it any less impressive W hen you blow up the balloon, set your racer down, and let it go, escaping air from the balloon rushes out of the straw causing propulsion.The principle at work is Newtons Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In the case of the Balloon Powered Car, the action is the air rushing from the straw. The reaction is the movement of the car The moving Balloon Powered Car has kinetic energy, but even an object that isnt moving has energy. This energy is called capability energy. The potential energy of the car is in the elastic material of the balloon. As the balloon fills with air, it builds more potential energy. As the air flows from the balloon, it changes to kinetic energy. This is the conservation of energy.
