Why do roller coasters have teardrop loops?

They gain their energy at the beginning of the ride, when you are dragged up a hill then released to race towards the ground, and this energy needs to be maintained throughout the length of the ride. Circular loops allow this energy to be maintained because the loops are teardrop shaped rather than a perfect circle.

Greater speed meant a much greater force on the rider as he entered the loop, which could be fairly uncomfortable. The teardrop design makes it much easier to balance these forces. The turn is much sharper at the very top of the loop than it is along the sides.
