Where do you feel the most force on a roller coaster?
At the bottom of the loop, gravity and the change in direction of the passenger's inertia from a downward vertical direction to one that is horizontal push the passenger into the seat, causing the passenger to once again feel very heavy.

The best seat on a coaster, then, is a matter of personal taste. If you love the feeling of weightlessness, head for the back.If you want the best view of the action, head for the front. The cars in the middle provide the weakest ride, but it's a good bet you'll still have a good time.
The normal force however has a small magnitude at the top of the loop (where the rider often feels weightless) and a large magnitude at the bottom of the loop (where the rider often feels heavy).
Riders may experience weightlessness at the tops of hills (negative g-forces) and feel heavy at the bottoms of hills (positive g-forces). This feeling is caused by the change in direction of the roller coaster.

Roller coasters are generally designed to have non-zero but fairly small normal forces at the top, so a rider feels almost weightless. At the bottom of the loop, the apparent weight can be considerably larger than mg, so a rider feels much heavier than usual.

This force is centripetal force and helps keep you in your seat. In the loop-the-loop upside down design, it's inertia that keeps you in your seat. Inertia is the force that presses your body to the outside of the loop as the train spins around.
How safe are rides? According to IAAPA, there are 0.9 injuries per million rides and that in a typical year, more than 385 million guests take more than 1.7 billion rides at about 400 North American fixed-site facilities.
People with high blood pressure and/or heart conditions are warned not to ride roller coasters because of the way they tax the cardiovascular system. The adrenaline rush that roller coasters give you causes a rapid spike in your heart rate and blood pressure.

Most coasters don't have a posted weight limit but if they do, that would be listed on the sign where the height restrictions are when you get in line. It's more common to see weight limits on water rides like water slides, and some kiddie rides where parents ride with kids.
Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.

It suggests that the chances of being killed on a rollercoaster are just one in 170 million, while the injury odds are approximately one in 15.5 million.
