Here's the Challenge

Yesterday, my teacher handed out a project that my honors physical science class was to complete. The challenge he gave us was " Apply your knowledge of Newton's law of motion, momentum, and energy to design and construct a vehicle that will go as far as possible using an unbalanced force to create motion." 

So here are the RULES:

• - Construct a vehicle that can travel at least 3 tiles(each tile is 60 cm)*. Vehicle must stay within a 2-tile wide path
• - No FORWARD force may be applied to vehicle by the student (me)
• -Vehicle must be made of recycled/reused products. No pre-made vehicle parts( other than axles and wheels) 
• - Vehicle must travel using an unbalanced force to create motion 
• - Students are not allowed to help vehicle along the path 
• -Students may not use electricity/ fuel cells or manufactured containers of pressurized gas( i.e CO2). This is a land vehicle. All vehicles start from a level surface( no ramps or strings). All parts of vehicle must remain on vehicle, except fuel. 

*to get full credit, the vehicle must go at least 5 tiles( 300cm)
