direction.) accelerating reference frame in the above example is accelerating with your car. Okay. an accelerating object is the vector sum of its real weight and $\vec{n}$ is the normal force exerted by the structure on the car. If you travel in a curved path in a vertical plane, then when you go over the top on such a path, there is necessarily a downward acceleration. I don't mean that standard value of $g$ define by some commitee. gravitational force would be zero, and your apparent weight would be zero. There are a few factors that might cause some people to develop abdominal fat more so than others. I assumed he was essentially just interested in the inverse-square law, whereas you are taking accelerations into account. Overweight Calculator That roller coaster ride exerts very strong g forces on the riders, up to about 5.9 g. The Vomit Comet was an airplane NASA used to accommodate astronauts to a zero g environment. In that case, this would make your apparent weight equal to your actual weight but that's wrong.
