Have You ever before Wondered... Can human being stick to walls? What is centrifugal force? walk the Gravitron defy gravity?
You are watching: What is the speed of a person “stuck” to the wall?
Today’s Wonder that the day was inspired by Evan. Evan Wonders, “how do you stick to a wall when miscellaneous spins really really rapid like the gravitron” thanks for WONDERing through us, Evan!
Do girlfriend love amusement parks? that doesn"t, right? indigenous the parking lot, you have the right to see the glowing lights and hear the shrieks that excitement. When inside, your nose will conveniently pick up the odor of every sorts of treats, such as corn dogs and funnel cakes.
The real fun starts as soon as you gain in line because that a ride. Will it it is in a thrilling roller coaster? maybe you prefer the stomach-churning Tilt-A-Whirl? Others could enjoy the bumper cars or the Octopus.
If you"re brave and also don"t mind defying the regulations of physics, there"s another ride that might beckon come you. It looks a little like an extraterrestrial spaceship. When you step inside, you heat up against the wall, your ago pressed right into a rubber pad.
As the ride starts to spin in ~ a price of 24 revolutions per minute, you feeling yourself pressed into the wall. Suddenly, the floor drops far from your feet and also there friend are: stuck to the wall with nothing listed below your feet, seemingly defying gravity.
What is this magical ride? It"s the Gravitron, of course! depending upon where friend live and also what amusement park, carnival, or fair you walk to, it may go by among several various other names, consisting of Starship 2000, Starship 3000, Starship 4000, and Alien Abduction.
Riding the Gravitron may seem favor pure fun, but there"s a many science walk on in its operation. To completely understand how the Gravitron works, you need to understand some advanced physics. However, we"ll take it a look in ~ a few of the basic forces in ~ work.
As the ride speeds up, you feel yourself gift pushed right into the wall behind you, away from the center of the ride. This emotion you suffer is referred to as centrifugal force, but it"s no actually a genuine force.
The suffer of centrifugal pressure is actually the an outcome of the mix of pressures acting upon your body throughout the ride. The rotation and acceleration of the Gravitron would tend to press your human body in a straight path off that the ride. Why doesn"t that happen? The walls of the ride hold you in.
While it may seem like there"s a force pushing you far from the facility of the ride, the force actually working on friend is the pressure of the wall pushing against you, keeping you from complying with your organic trajectory, which would certainly be a straight course off the ride. This pressure is well-known as centripetal force, because it"s directed towards the facility of the ride.

So why don"t you loss down once the floor that the Gravitron lowers? go the drive defy gravity? not quite! together the wall pushes on your body, her body pushes back against it. Newton"s 3rd Law of motion holds the for every activity there is one equal and also opposite reaction.
As your body and also the wall push versus each other, the pressure of friction keeps you in place. While heaviness is tho present, the pressure of friction between your body and the wall surface can be tantamount to three times the pressure of gravity, thus preventing you indigenous falling once the floor disappears below your feet!
