Why do we feel uneasy when Ferris wheel moves downward?
Answers
When the Ferris wheel moves downward, we feel uneasy because our reaction force is somewhat less than the regular reaction force.
When we are on Ferris wheel, there are two forces acts on a person, a force due to gravity, and the other is centrifugal force of the wheel rotation.
When we are moving upwards on the wheel, than we feel more heavier, while in case of moving downward we feel lighter as acceleration of the wheel is in the direction of the gravitational acceleration.
One feels uneasy because the Ferris wheel spins the seats can freely rotate at the support where they are connected to the wheel.
The Ferris wheel spins upwards with the help of motors and gears, while gravity pulls the wheel back down again. This rotation continues for the duration of the ride.
