I’m all about Falcon and the Winter Soldier—The latest Marvel show at Disney +. Don’t worry, I won’t hurt anyone seriously. I just wanted to talk about the winguits in episode 1. Sam Wilson (Falcon) faces a hostage situation aboard a military plane. The bad guys took their hostage and jumped out of the plane wearing wings. If you haven’t seen it yet, they’re actually sculpting heavenly outfits with extra material between the arms and legs to make them look like wings – that’s the name
The hostage had no wings, so they tied him to the back of one of the reprimanded bad guys. After that, the Falcon runs in pursuit and has a few things in motion – see, there’s no real robber.
But really, this is just a chance to talk about some fun physics. So, let us consider the following two questions. One: How fast can a winged man fly? Two: What happens if there is an extra person (a hostage) behind a jufper winguit?
Let’s start with something simple and then make it more complicated. (That’s what we like to do in physics.) Suppose you jump out of an airplane and there’s no air at all. Yes, that’s weird-but just think. For this case, there is a force that moves you-the force of gravitational bringing down due to the interaction between you and the Earth. Gravitational force can be calculated as a product of your mass (in kilograms) and gravitational field (we use g for this). Until you are within about 100 kilometers from the Earth’s surface, the gravitational field is about 9.8 new per kilogram.
What has this ever -decreasing gravitational force done to a world without air? There comes Newton’s second law. It gives the following relationship between energy and acceleration:
Two important notes. First, the same force and acceleration are vectors. (That’s why they have an arrow on top of them.) This means the same size and direction cause. Second, this expression refers to the force of the net (the total strength). Since the force is only gravitational, you will speed towards the bottom – your speed will continue to increase until you fall. But that’s just pure fall and not wing flying.
