WebWithout collisions with other molecules it can travel upwards h = v 0 2 2 g = 9 kilometers before the gravity stops it and pulls back to Earth. Basically, potential energy of molecules in gravitational field is too small compared to their kinetic energy to keep them low. Web6 de jan. de 2024 · And the idea of gravity as a simple up-down force happening purely on Earth is very wrong too. Gravity is like invisible elastic stretched through the whole universe, holding the stars and planets together and pulling them toward one another. flying j truck stop peculiar moWebAsked by: Tim Redgood, Ashford. Strictly speaking, the Earth’s gravity will always pull on an object, no matter how distant. Gravity is a force that obeys an ‘inverse square law’. So, for example, put an object twice as far away and it will feel a quarter of the force. Put it four times further away and it will feel one-sixteenth the force. flying j truck stop shower prices

"WebYou basically end up with a simple relationship: for the same gravity, the ratio of the planet’s radius to that of Earth equals the inverse ratio of their densities. Earth is the densest (~ 5.5 g/cm^3) of the rocky planets in our own solar system. " - How come earth has gravity

Web24 de jan. de 2024 · Deep below ground, the solid core of the Earth generates the planet’s magnetic field. But in a flat planet, that would have to be replaced by something else. Perhaps a flat sheet of liquid metal. That, however, wouldn’t rotate in a way that creates a magnetic field. Without a magnetic field, charged particles from the sun would fry the planet.
