Why dont people fall out og roller coasters at the amusement park?

Answer 1

Water swirls down a drain because the hole that the water is sucked down into is small to create a tornato. Water swirls down a drain because of gravity force. Water swirls down a drain because the world rotates all the time, creating a round or swirl movement in a drain.

Answer 2

A invisible force (Called G-Force) pushes you back in your seat or there isn't enough airtime to lift you off the car. Another reason is you have a restraint (Seatbelt like mechanism which is locked during the duration of the ride) is in place and stops you falling out.
Sometimes they do. Mostly though, the roller coaster is moving at significant speed and so are you. If the car is upside-down, you are usually moving in a circle quickly, meaning you have a speed in the direction opposite to gravity. For gravity to change this speed and make you fall takes more time than you usually spend up-side-down.

Answer 3

Well, the rollercoaster train is suspended from the track, and you're strapped in to the train!

Seriously though, even if this were not true, you would not fall out at the top of a loop - provided you were going fast enough. When we start moving, we have something called inertia, which means an inherent resistance to a change in that motion. If you stand in front of your friend whist she runs at you, you'll feel her inertia: it takes effort to stop her.

The important point about inertia here is that it is directional - it has a direction associated with it. When you turn a corner in your car, it's your inertia that pushes you against the door of the car, as your inertia was pointed in the direction you were travelling before the car cornered. The car door (and friction with the seat) has to push against you to change the direction of your inertia, just as friction between the tyres and the road change the car's inertia.

This is how it happens. If you're going fast enough, your inertia (and that of the rollercoaster train) is alwayspointing into track as you go around the loop. The track pushes back, changing your inertia and making you loop. Gravity is also acting, and at the top of the loop is also changing the direction of your inertia, towards the ground. But - if you're going fast enough, gravity cannot change your inertia enough to make you come off the track. Quite the opposite - rollercoasters are designed so that you go round the loop much more than fast enough, so that in fact, you always feel pushed down into your seat: that's your inertia pushing down into the train whilst the train and gravity change it's direction.

So that's whats physically happening - but you might hear other descriptions. A 'shortcut' to this lengthy description is to say that circular motion requires a centripetal acceleration, and at the top of the loop, gravity just provides (or fails to provide so that the track provides it) exactly the centripetal acceleration required for that size of loop. Now this is fine if you're a physicist, mathematician or engineer, because you understand what's lurking behind each of those statements. But it doesn't tell you anything physical about the situation unless you already understand these things.

Answer 4

Acceleration causes you to always be in motion. Plus, rollercoasters have to be up with the current safety standards, so there is lap bars, seatbelts, and over the shoulder harnesses when they're needed, if the case is that you'd fall out without them.

Answer 5

Two reasons.

First, every roller coaster that I am aware of which features an inversion has serious restraints; you could literally hang upside down in one without falling out ... it wouldn't necessarily be comfortable, but you wouldn't fall out.

Second, the coasters are designed so that inertia keeps you in your seat even during inversions.

Answer 6

When a roller coaster enters loop-the-loop, several forces (except safety precautions) like inertia, gravitational force etc. act on it and prevent people from falling to the ground.

Answer 7

They don't fall out of the roller coaster because they are strapped.
