Name: _________________________________ Date Due: ________________________ Balloon Car Project Each student will design and build a toy car which is powered by a 9 inch round balloon. In class, each student will then time how long their car takes to travel the one meter from the start line to the finish line, calculate the average acceleration of the car over that one meter distance, and show how Newton’s second and third laws apply to the motion of their cars. Materials: 1 – 9 inch round balloon Additional “add-on” materials as needed Rules and Remarks: 1. The vehicle must maintain at least 3 points of rolling contact with the floor at all times. 2. The vehicle can only be powered by one 9 inch round balloon. 3. The wheels and axle used on the vehicle cannot have been professionally manufactured for that purpose. Grading: 70 points will be awarded for building a car which can move across the floor from the start line to the finish line 1 meter away. Cars that do not cross the finish line will receive 60 points. 10 points will be awarded a correct calculation of the car’s acceleration over the 1 meter distance. 10 points will be awarded for a correct calculation of how Newton’s Second Law applies to this project 10 points will be awarded for a correct explanation of how Newton’s Third Law applies to this project Points Awarded 60 points Car meets all rules and regulations 10 points Car crossed the finish line 10 points Correct calculation of acceleration Given Formula d = 1 meter t = _____ sec Substitution Answer with Units a = 2xd t2 10 points Newton’s Second Law states that the force of an object is equal to the acceleration of that object times the mass or F = ma. Use a balance to get the mass of your car and then calculate its force. Given Formula Substitution Answer with Units 2 a = ____ m/s m = _____ g or F = m x a _____ kg (kg) (m/s2) 10 points Newton’s Third Law states that for every action there is an equal but opposite reaction. Explain how this applies to your balloon car: Use complete sentences! Name: _________________________________ _______ / 100 Total Points Date Due: ________________________
