Project 3: Energy Car Duration: 6 cycles
Project 3: Energy Car Design Brief: The power of a car is come from the engine. No matter it is petrol engine, diesel engine or electrical engine, is also the process of changing energy. Try to use a steel wire to store the energy for providing power to the car.
Project 3: Energy Car Requirement: The steel wire is the only energy provider, no other power is allowed. The steel wire must be the part of the car, not to be a shooter.
Project 3: Energy Car Requirement: 3. There is no size limit for the car. You may put materials in your design other than provided. 4. Longer distance running is recorded, higher mark will be given.
Project 3: Energy Car Material provided: Balsa, 900 x 10 x 10mm Foam Board (High density rubber foam), 5mm thickness Steel wire, 17 swg (Ø1.4mm) Cotton string Wooden rod, Ø5mm Hot glue Cable ties
Project 3: Energy Car Assessment criteria: Product: Appearance – 30% Distance run – 70% Folio: Full steps – 50% Show ideas clearly– 30% Drawing quality – 20%

Project 3: Energy Car Friction Energy storage: Steel Wire Potential Energy Kinetic Energy Resistance: Friction
How to make it running farthest distance? ~ Increase the effective length of the wire ~ Increase the diameter of the driving wheel
2. Lighten the weight of the materials
