In fact, the reason is quite simple, but you may not have thought about this detail while watching the movie. After all, the number of remarkable details in the movie was quite a lot.
Instead of giving the answer to the question with formulas, we will give it in simple language and with examples, as if you were telling a child. You will immediately understand why.
The ring-shaped vehicle rotates around itself, creating an artificial gravity. It does this with centrifugal force.
Without this artificial gravity, Cooper and his team would not have been able to stand comfortably like this.
They should have glided forward like astronauts on the International Space Station.
When the gravity factor disappeared, they had to glide.
In the other vehicle, there was no artificial gravity.
So how does this artificial gravity happen?
During very long space travels, astronauts lose muscle and bone due to the absence of gravity. Gravity was created in this way so that the crew in the film would not be affected by this, and the simplest way to do this is to rotate the spacecraft in this way.
Thanks to the centrifugal force, whatever is inside the spacecraft sticks to the vehicle, in other words, they can have a weight in space.
Let’s make the situation clearer with a simple example:
The reason why the water in the bucket does not spill when you turn a bucket full of water in this way is based on the same physics law.
The force created by this rotational movement is also called the “centrifugal force”. The faster the rotation speed, the stronger this “gravity” feeling.
This force depends on the rotational speed and the radius of the turning circle. That is, the higher the rotational speed or the larger the radius of the turning circle, the greater the centrifugal force.
For example, when a car is cornering, a force is felt towards the outside of the car. This creates a kind of centrifugal force effect. The feel of this force can mimic gravity, so it is often used in gravity simulations in spacecraft.
Consisting of a series of modules, the Endurance will break apart if it spins faster, especially if it goes beyond the limits of its design, due to the increased centrifugal force from that spin.
Also, a vehicle that rotates too fast makes it difficult for astronauts to move around and do their jobs. Physiologically, it also causes them discomfort. For these reasons, the rotational speed of the spacecraft is kept at an optimum level.
We saw a similar situation in 2001: A Space Odyssey.
In this way, people in it could move freely.
So who thought of Newton’s 1st Law while watching these movies?
