I’m huge Fan Star Wars. The first film (no, not episode 1) appeared when I was adolescent, so I grew up, thinking about Millennium Falcon and lightweight swords. Perhaps this caused my interest in science – even if it is not exactly science fiction. Oh, Is A nice way to start fighting Kejon: “Science fiction” Star Wars, is it a “cosmic fantasy”?
Anyway, you must admit that there are things Look Like learning. I mean that every time you are dealing with things in space, this is an opportunity to talk about science. This is what I’m going to do because today is Star Wars Day. Let the fourth be with you!
What scientific things in Star Wars are simply not scientific? I intend to go to some more intriguing ideas, but don’t get me wrong. I operate these mistakes as a way to talk about science, but I don’t think to fix them. More realistic Star Wars would probably be uninteresting. Read on, you’ll see what I mean.
Sound in space
Opening scene Star Wars It shows a massive destroyer of the star who is chasing a smaller rebel ship. You hear the rumbling of engines and it gives the impression of a powerful dish. Unfortunately, this is simply not possible.
Let’s think about the sound for a moment. Suppose you touch the cup aside with a spoon. You hear a nice little plink. This is because the tap caused that the ceramic material oscillates there and back, which pushes around it, squeezing it. This compressed air is pushed to other nearby air as it develops. The whole process produces a wave of pressure, and this pressure wave is what we call sound.
Can you have a sound wave without air? Vivid. You don’t need air, but you need something So that the pressure wave can pass. It can be solid, water or really everything that allows less pressure for parts at lower pressure. Sound waves need a medium for “waving”. There is … nothing in space.
It is not entirely TRUE. There are charged molecules such as protons and electrons moving in space – devoid of sun wind or debris from explosive stars. There is also some dust in the solar system. Despite this, the density of this “gas” would be so tiny that you could barely measure it. Much too low to send sound.
So why are Moviemakers put the sound in the void? Well, most of us have never been in space, and when everything collides, they just seem bad. The sound of this huge star destroyer reminds us of a huge ocean vessel passing nearby – something that we can relate to.
How do you manage it?
One of the biggest ideas in physics is that forces change the movement of the object. If you apply a constant, continuous strength to the object – and there are no opponents such as wind resistance – this object will accelerate and To continue Accelerate forever.
We call the second law of Newton and it works for many forces on the object, replacing them with one force called net force, as shown below. Here M it is a mass of a spaceship and AND It is his acceleration.
