The minimum speed they need is called the critical velocity and has a mathematical computation coaster designers must follow to make a successful ride. As a safety precaution, most coasters have wheels on both sides of the tracks to keep the cars from falling.

Humans are used to feeling 1 g, which is the force applied by gravity while standing on Earth at sea level. But when a roller coaster crests the top of a big hill, the acceleration is subtracted from 1 g and we feel zero g or negative g. That ride has a G-force of 6. Comments: erin.

As the train cars approach the loop, your inertial velocity is straight ahead of you. But the track keeps the coaster car, and therefore your body, from traveling along this straight path. The force of your acceleration pushes you from the coaster-car floor, and your inertia pushes you into the car floor.

Your own outward inertia creates a sort of false gravity that stays fixed at the bottom of the car even when you're upside down. You need a safety harness for security, but in most loop-the-loops, you would stay in the car whether you had a harness or not.

As the cars move through the loop, the net force acting on your body is constantly changing. At the very bottom of the loop, the acceleration force is pushing you down in the same direction as gravity. Since both forces push you in the same direction, you feel especially heavy at this point. As you move straight up the loop, gravity is pulling you into your seat while the acceleration force is pushing you into the floor.

You feel the gravity pulling you into your seat, but if your eyes are still open you can see that the ground is no longer where it should be. At the top of the loop, when you're completely upside down, gravity is pulling you out of your seat, toward the ground, but the stronger acceleration force is pushing you into your seat, toward the sky. Since the two forces pushing you in opposite directions are nearly equal, your body feels very light. As in the sharp descent, you are almost weightless for the brief moment when you are at the top of the loop.

As you come out of the loop and level out, you become heavy again. The loop-the-loop is amazing because it crams so much into such a short length of track.
