drop it on me dear Tim and Moby how do we stick to the Earth why don't just fly off into space from Chrissy in the space whatever let's talk Gravity movie let go of that Apple towards the Earth and hit me along the way there's a reason that I just fall to the ground instead of flying off into space this reason is a force called gravity gravity pulls objects together everything in the universe has gravity feed the Earth the Sun the Moon Apple's Avenue in 1687 a scientist named Sir Isaac Newton gravity reason that gravity depend on mass and distance massive objects exert a stronger been less massive objects an object that are far apart is there less gravitational force on each other than objects that are close together in a 20th century Albert Einstein expanded on Newton's ideas with his theories of relativity according to Einstein's theory of general relativity massive objects actually been space and time we could have like this if you put something massive on a trampoline like a bowling ball the surface sinks in a little put a light object nearby like a marble and it rolls towards the bowling ball back to our question first gravitational field pulls you toward the center of the earth since all objects possess a gravitational field you're actually pulling the Earth Tour since the Earth is so much bigger than you you don't really feel it an object's Mass isn't the same thing as its weight Mass has to do with the amount of stuff in an object is the force exerted on an object's mass by gravity the moon an apple weighs 1/6 as much as it does on Earth if the same Apple but the moon's surface gravity is weaker because the Moon is only 1/6 the size of the Earth week or surface gravity means that astronauts can jump 6 times as high who is they can at home the moon's gravity pulls at the Earth causing Tides gravity keeps the moon orbiting around the Earth and the Earth orbiting around the Sun gravity even hold the planets and stars together gravity is one of the most forces in the universe as far as we're concerned without it even have a place to stand on
