dewes Posted November 10, 2017 Share Posted November 10, 2017 As a engineer student, i have studied alot of physics, and i want to give feedback on the gravity system that pull the drone to a point in the center of the planet. thats not how things works. in our planet Earth, the gravity on the surface is approximately 9.8m / s², the gravity force gets weaker if you go under the surface. The deeper you go, the weaker is the gravity, until the center where it's null, it exist, but the resultant force is zero. Link to comment Share on other sites More sharing options...
DarkCrystal0 Posted November 10, 2017 Share Posted November 10, 2017 no your wrong dude the closer you get to the planet the faster you go towards the center Link to comment Share on other sites More sharing options...
Kadan Joelavich Posted November 10, 2017 Share Posted November 10, 2017 No, he's right. Gravity is a force exerted by mass and thus a property of all matter. In the absence of any other stellar bodies even two humans would exert a noticeable gravitational effect on each other. As an object passes through a planet the mass of all the stuff (dirt, magma, trees, walruses) above the object are also exerting gravitational force. That's why in the center of the planet the object would be "weightless" because gravity is pulling it equally in all directions. That having been said, an object at the center of a planet would also be subject to enormous pressure which would more than make up for the lack of gravity. My physics based complaint is that as you destroy significant portions of the planet's mass, the gravity exerted on you remains unchanged. In theory if one vaporized an entire world, there would be no gravitational pull at that location anymore. Link to comment Share on other sites More sharing options...
