It seems like there are two ideas about gravity vehicle going around. One idea was that the car would be propelled by a falling mass, presumably pulling a string to turn the wheels. But other sources say like an eggless scrambler. From my kowledge of scramblers, they were pushed by a swinging mass of some kind, but then just coasted. So which is more accurate? Does the power source travel with the car? Just so I can begin to conceptualize some plans.

The second one is closer, but still not quite there. It will be a vehicle travelling down a ramp, propelled solely by its own mass.

Will we be building the ramp, or will we just build the cars that roll down a standard ramp for everyone? This isnt what i expected.

awww man. come on chalker, I expected to build some crazy-complex thing that uses a falling mass that is mounted on the vehicle with like 29 pulleys....
way to rain on my parade =P

So a ramp huh? is it steep? will there be a set pitch for the surface?

There are maximum external dimensions, but beyond that it's up to your own design.

any hints on what the scoring will be like? is it just hitting a point as quickly and accurately as possible?

Just wanted to point out it's my brother 'chalker7' that's raining on your parade. As for myself, 'chalker', it's always sunny, just like in philly;)

Yes, measurements of various types will be made, and those will go into a formula to calculate the result. Low score wins;)

Yes, and ideally you'll want your vehicle to go as quickly, as accurately and as close to your predicted time as possible

Not to mention, heh, that you use gravitational potential energy as the vehicle's sole means of propulsion to reach a Target Point after, in fact, you design, build and test one vehicle and ramp. :P
