Question

Why do we feel uneasy when the Ferris wheel moves downward?

Answer 1

Ferris wheel:

1. The virtual force operates downward when the wheel is rotating upward. Because of this, the net normal reaction on us increases.
2. A virtual force would be any equilibrium system of forces. For example, f(x) and y(x) are actual forces and displacements. y(x) represents a virtual displacement that is compatible with the perimeter constraints.
3. The natural reaction of the wheel to us as we move downward with it diminishes proportionally as the virtual force begins to work upwards at that point.
4. This is the energy that makes us nervous. Because of this, we have a sense of lightness and impending flight or wheel-fall.

Therefore, as a result, we feel lighter and as if we're about to fly or fall asleep behind the wheel.
