Right before the coaster causes gravity to push down more on your head or chest (traveling upwards), you feel that stomach-in-your-throat feeling (traveling downwards). Of course, the opposite is also noticeable. Also, if you have ever been on a roller-coaster, and you travel into one of the sharp valleys on the coaster, you feel like something is pushing your head down, or pressing into your chest right? That’s the G-force making you feel heavier (you of course don’t actually get heavier). This rapid increase in velocity effectively changes the G-force on your body. When you are traveling by plane and you take off, the plane accelerates to very high speeds in order to do so. My point is that we are very well-equipped to deal with our own planet’s gravity, or 1 G, and the only time we notice this force is when it becomes higher or lower than 1 G. Were you to travel to a planet that had a more significant gravity, a more massive planet with 5 G’s for example, you would either be unable to lift yourself off the ground, our the new weight-force would be so much that the air would be forced out of your lungs and your eyes would explode (something gruesome for sure). I use the term “weight-force” because, as will be explained below in the “Physics” section, our mass remains constant and the gravity changes.Įvery bit of our muscular-skeletal system is naturally crafted to deal with Earth’s gravity. You don’t notice it because that is the weight-force that we have evolved to endure. When you are there, sitting and looking at the screen, you are experiencing 1 G. ![]() ![]() ![]() So what does a “G” feel like? Well actually you are feeling it right now. What we will explore below is some facts and STATA (stats and data) on G-forces humans have subjected ourselves to, the basic reasoning and math behind the “G-force”, and marvel at how natural selection has produced, in effect, the world’s best shock absorber. You may have heard that astronauts and fighter pilots go through rigorous and vomit-inducing training to combat this, but how has nature dealt with this problem? If the fighter pilot can just barely handle 10 G’s, how could a woodpecker withstand 1200?! The “G-force” as it is called, determines the force imparted to objects, depending on the available gravity.
