The second car didn't fully clear the edge of that final jump though. Bounced really nice.

It still "appeared" slow when they reached the top of the loop, even though they experienced around 7g's inside the loop.Foil wrote:Cool!

1. There's a difference in scale, but no difference in gravitational acceleration. [To visualize the difference, imagine the car falling from the top of the loop - it would take considerably longer than it takes a toy car to fall from the top of a toy loop.]
2. Little toy Hot Wheels cars need to be given enough momentum to carry them through the loop. Those cars didn't need as much momentum, because they provide some of their own force while driving through the loop. [This one is analagous to the reason why rockets don't have to reach escape velocity to get into space.]
