After analyzing acceleration data, it was determined that the front row had the greatest negative acceleration in the z direction and was therefore the “best place” to sit. Most people who enjoy roller coasters have a favorite place to sit when riding, but no quantitative reasons for sitting there.
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.
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.
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.
