Accepted Answer
Your kinetic energy is always proportional to the square of your speed, no matter whether you're on a bicycle, a roller coaster, or a baby carriage.The faster you're moving, the more kinetic energy you have.Your potential energy doesn't depend on speed at all, only on height. On a roller coaster, the minimum speeds are usually at the top of a hill or a loop, so the potential energy would generally correspond to the slowest speeds. But again, that's not because of the speed. It's because of the height.

the slower you go, you will eventually stop, p. energy. faster=k. energy.
