At what point does an object experience the greatest G-Force?

An object experiences the greatest G-Force when it is going into and coming out of loops. This occurs because G-Force is related to the acceleration experienced by the object, which is significantly influenced by changes in direction and speed.

When an object, such as a roller coaster, enters a loop, it has to accelerate upward against the force of gravity to stay on the track, resulting in an increase in the force felt by the riders. As the coaster moves through the top of the loop, the riders experience a sensation of weightlessness or a reduction in G-Force since gravity is pulling downward while the track pushes upward. However, as the coaster exits the loop and begins to descend, the riders feel a sharp increase in G-Force again due to acceleration downward combined with the force of gravity.

At high speeds, while there may be increased forces due to inertia, it is the rapid changes in direction during the loops that create the most significant G-Forces rather than just speed alone. When an object is stationary, it does not experience any G-Force from acceleration, and during free fall, while gravity is acting on the object, the sensation of G-Force is typically less prominent as the object and any passengers are in a state
