Why is responsible for the apparent change in weight that riders experience on a rollar coaster?

The apparent change in weight that riders experience on a roller coaster is primarily due to the forces of acceleration and deceleration during the ride. As the coaster moves through loops, drops, and turns, it creates varying gravitational and inertial forces that can make riders feel heavier or lighter than their actual weight. For instance, at the top of a hill, riders may feel lighter due to reduced gravitational force, while at the bottom, they may feel heavier due to the increased force from acceleration. This sensation is a result of the dynamic interaction between the coaster's movements and the forces acting on the riders.
