Explore artificial gravity as we break down the science behind the Netflix movie Stowaway.
How does that rotation make artificial gravity? Let's start by imagining a human sitting in a stationary chair on the surface of the Earth, perhaps just like you are doing now. There are two forces acting on the person. First, there is the downward-pulling gravitational force—this is equal in magnitude to the mass of the human multiplied by the gravitational field . The other force is the upward-pushing force from the chair on the human's butt.
For this thought experiment, let’s replace our human with a spring connected to a single mass. As we know, if I place this mass-and-spring combo on a floor on Earth, the gravitational force pulls down on the mass and the floor pushes up. The combination of these two forces will compress the spring. But let’s say we try this on the floor of a ship in outer space, where there is no gravitational force. I can create this compression by instead making the floor accelerate upwards.
app to plot the angular position as a function of time. The slope of this data will be the angular velocity. Here's what I get:The slope of this line is 0.1024 radians per second. If that's the angular velocity, then what circular radius would you need to get an artificial gravity of 0.5 g?Let's just make it simple: To achieve an artificial gravity of 0.5 g, you’ll need a radius of 450 meters and a spacecraft-to-counterweight distance of twice that ..
But that's not very exciting for a movie. So here is something very dramatic instead. Suppose an astronaut starts near the center of rotation with very little artificial gravity. Instead of slowly climbing "down" the tether, what if they just let the fake gravitySince the force on the astronaut changes as they move down, this becomes a more challenging problem. But don't worry, there's a simple way to get a solution. It might seem like a cheat, but it works.
