V1011 Pennsylvania College of Technology Resource #4 Name: _______________________________________________________________________________________________ Going Off-Road With Sir Isaac Newton Consider the video you just viewed, ’degrees that work’: Advanced Manufacturing. Select at least 3 elements or events you viewed from the video that demonstrate direct application of at least one of Newton’s Laws of Motion. Using the chart provided below, list the element or event you observed in the video, the law demonstrated and a brief explanation of how the element and law are linked. Explanation Video Element/Event Newton’s Law Demonstrated Note: Add additional examples as classmates share their ideas. Resource #6 Balloon Rocket Car A rocket is simply a chamber filled with pressurized gas. A small opening called a nozzle allows the air to escape, causing thrust that propels the rocket. You can demonstrate this when you blow up a balloon and let it go without tying it off. The balloon will fly through the air as all the air inside escapes. Sir Isaac Newton laid the foundation for the modern science of rocketry near the end of the 17th century. Newton's Laws of Motion are essential to rocket flight. Here are two of them: Newton’s Third Law of Motion: "For every action there is an equal but opposite reaction." When an action takes place, like gases escaping from the rocket, a reaction follows - the rocket rises in the air. Newton’s First Law of Motion: "Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force." In other words, the forces pushing a rocket up must be stronger than the force of gravity pulling it down. The principles of rocketry apply to more than flying rockets - with this project you can make a "rocket car" that is powered by pressurized gas (air in a balloon!). 1 Resource #6 GOAL: Apply physical science and basic manufacturing concepts to build a “balloon-powered rocket car” that will travel the farthest distance from a starting point. GUIDELINES AND RULES: Your challenge is to construct a vehicle powered only by the release of air from the attached balloon. You and a partner will be provided with a bag of materials that includes the following: 2 wooden axle rods four wheels 2 long bendable straws (one for each member) 1 long straight straw (cut to form axle housing) 2 Popsicle sticks 1 9” balloon 1 rubber band Prior to competition, each car will be subject to inspection from the teacher and any other judges, as specified. At this time, the length and mass of each car will also be recorded. After this point, no changes may be made to the car. Each car will be given the opportunity to make two runs. The maximum distance achieved in these runs will be used to calculate the winning car. If a tie occurs, a third run will be granted to both vehicles. The winner will be determined by this third run. You will have access to glue (regular and hot glue), tape, markers and other basic supplies here at school. You may use the materials provided, or bring any in from home. No pre-made kits or prefabricated cars may be used. The supplies you will be given will be enough to construct a very basic balloon-powered vehicle. You are strongly encouraged to bring in other supplies you think would allow you to build an even better vehicle. No gases other than the air you exhale may be used. No other propulsion systems are permitted. Cars must have a minimum of 3 wheels. No balloons larger than 12” in diameter may be used (you will be given a 9”/22.5 cm round balloon). If you wish to use a larger balloon, you must provide it. Balloons can be inflated to any size, as long as they do no burst. Should your balloon burst or become damaged on the day of the race, you will be given only 1 replacement balloon. Cars that interfere with other cars during the races (i.e. they do not travel straight) will be disqualified (wheel alignment is critical). 2 Resource #6 Balloon Rocket Car Car Construction Basics: Tape the Popsicle sticks together to form the body of the car. Cut the straight straw in half. Use 1 of each half to hold an axle so that it spins freely. Tape or glue the straws to a stick. Use a rubber band to attach the long, bendable straw to the balloon. Blow up the balloon and tape it to the car. When constructing your vehicle, consider the following important questions: What can I do to reduce the fluid friction on my car? -Have I made changes to reduce the air resistance on my car? -Have I created a design that is aerodynamic? What can I do to reduce the rolling friction of my car? -Have I effectively reduced the mass of my car? -Have I examined the friction between my car and the floor? -Have I examined the friction between my car’s body and the axles? In order to propel my car forward, have I created a net force that is as great as possible, as permitted by the competition’s requirements? Are my car’s wheels aligned? 3 Resource #6 Balloon Rocket Car PRELIMINARY SKETCH In the space below, sketch your proposed car. Show your sketch to a teacher before constructing the actual car. List the materials you will be using to construct your car. Only include those that are DIFFERENT from the original bag of materials issued to you by your teacher. _______________________ _______________________ _______________________ _______________________ _______________________ _______________________ 4 Resource #6 CONSTRUCTION: 1. Cut the long straw in half. Each of these will house an axle. The housing should be a slight bit shorter than the axle itself. 2. Insert the axle rods into each axle housing. 3. You may want to glue one wheel onto each axle rod, then place the axle housing over the axle rod and glue the other wheel onto the axle rod. 4. Center the axle housings onto the popsicle stick(s) and/or whatever material you are using for the body of the vehicle. Use one axle/housing set for the front wheels, and another set for the back. Glue the housing into place. You may use whatever additional materials you have brought from home to add to the body construction of this vehicle. 5. Try your car. Place it on the ground and gently push it ahead. Does it roll with relative ease? If it does not, it is a good idea to check the axle housing. Is it a little too long, and rubbing the wheel? 6. Attach the bendable straw you have been given into the opening/neck of the balloon. Wrap a small, thin rubber band around the area where they touch to secure the balloon in place. Take special care not to wrap the rubber band too tight, or the straw will be crushed. Attach this balloon/straw structure to the vehicle. 7. Now, take it for a test drive! Gently blow up the balloon until it reaches its desired size. Then, quickly squeeze the opening of the straw to keep the air from escaping. Remove your finger from the straw, allowing the car to travel forward! 8. Carefully examine and refine your vehicle. Make any adjustments you think are necessary. 9. Measure the length of your car to the nearest tenth of a centimeter. _______ cm 10. Measure the mass of your car to the nearest tenth of a gram: _______ g 5 Resource #6 DATA COLLECTION TABLE Time (seconds) Distance (meters) Speed m/s Run #1 Run #2 Calculate the average rate of speed of your balloon rocket car.
