Does High Speed Or High Acceleration Provide The Biggest Thrill On An Amusement Park Ride'

Does high speed or high acceleration provide the biggest thrill on an amusement park ride'
It is not necessarily high speed or high acceleration that creates a thrill for the amusement park patron but instead it is the forces applied to the body during a ride forces created by high speed and acceleration. On amusement park rides there are two main forces acting on your body that you noticeably feel and enjoy. These forces are g force and centripetal force.
When a body is at a constant velocity all forces are in equilibrium. Imagine a car on the highway travelling at a constant velocity. We can say that after taking account of internal friction and the rolling resistance of the tyres we have an amount of thrust (force) that is equal to the amount of aerodynamic drag (force). Imagine now, that this car accelerates. At present your body should be experiencing 1G. This means that in our present gravitational environment all objects, if not already experiencing a normal force say, of the ground, will accelerate at 9.8m/s². If the car accelerates in a forward direction at 9.8m/s² you will feel a force equal to that of gravity, 1G, pushing
