We all know that gravity is the reason for things falling but nobody really knows why. We do know how to find and calculate gravity which helps us understand it better. Newtons law of universal gravitation helps to understand a little more of how gravity works. It states that any two things with mass have a gravitational force between them. The more mass and the closer they are means the more gravity they have. So all of us are pulling on everything with mass all the time but our masses are so small compared to the mass of the earth that it does not have an effect. The Law of Universal Gravitation does not just apply to objects on earth but the entire universe thats why its called universal. Using this law we can discover the gravitational force on any planet that we know the mass of before we even go there.
