At what point on a roller coaster would riders most likely feel 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.
The same can be said for this phenomenon on roller coasters. “You feel very light at the top of loops, but heavier than usual at the bottom” (Boston University).
When at the top of the loop, a rider will feel partially weightless if the normal forces become less than the person's weight. And at the bottom of the loop, a rider will feel very weighty due to the increased normal forces.
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.
In a typical coaster design, the riders in the front car get an unobstructed view of all these obstacles whipping past them. In a coaster that has seats facing backward, the rear car offers the best of both worlds -- you get a great view and the most intense ride.
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.
As your coaster tops a hill, the front car will seem to hang over the edge, but the rear car will whip over much faster. The middle seats have the weakest ride in terms of view and speed but they'll give you everything the seats in the front and the back do at just a little less intensity.
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.
A. Airtime – A favorite term for roller coaster enthusiasts! It's used to describe the feeling created by negative g-forces which gives riders the sensation of floating on a roller coaster. Airtime or negative g-forces are most commonly experienced on a drop or at the crest of hill.
Rollercoaster loops are most often not perfect circles – instead, they are teardrop-like in shape. This is because it takes a greater amount of acceleration to get the train around a perfectly circular loop.
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.
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.
“As far as an age limit, though, if you are physically healthy and up for the thrill, there is likely no greater risk for someone who is 60 than there is for someone who is 20.” The largest concern for those who indulge in roller coasters is the after effects.
Utah's S&S Worldwide, which makes roller coasters and drop towers, sets its restraints for a maximum weight of 300 pounds and equips its seatbelt locking mechanisms with no-go sensors that restrict over-sized riders.
