We are watching a movie! Haha no, We are learning about Gravity.

      Hello People! I'm going to go ahead and guess what you are doing right now. You're sitting down reading this blog. That part is kind of obvious, but how are you sitting down? Have you ever wondered how you don't just fly into the air? Well, some of you probably haven't recently because you know why :/. But anyway, the reason you aren't currently floating is because of gravity! If you know what that is, then you will understand this blog post very easily!

      Gravity is a force of attraction between all objects in the universe. We experience it every second of every day. Every thing in the universe has gravity. The earth has gravity! This is how you are standing up! The Earth has a gravitational pull that is pulling you towards the center of the Earth, but because you have a gravitational pull as well, you stand upright. The Earth's pull is larger, so you don't feel the pull. When you get into space, you are a certain distance away from huge objects that the force isn't strong enough. 

      This theory was introduced by Sir Isaac Newton. Here's that name again. He believed gravity had to do with two main things, mass and distance. Massive objects will exert a stronger gravitational pull than less massive objects. If two objects are closer together, than the force is stronger than when they are farther apart. Galileo Galilei made up a famous experiment testing gravity. He climbed up to the top of the Leaning Tower of Pisa and dropped two balls with different masses and similar shape. He learned that heavy things fall faster than light things. 

      An objects mass and an objects weight are very different. An objects mass is the amount of space the object takes up. An objects weight is the force exerted on an objects mass by gravity. If you move to the moon, your mass stays the same, but your weight changes. The amount of space you take up won't change, but the amount of force exerted will because it all depends on gravity. The moon is smaller, therefore it has a smaller gravitational pull.

      Did you know that gravity is one of the most important forces in the universe? Well, know you do! It is because gravity keeps everything in place in the universe. Gravity is why we aren't floating aimlessly in space until we hit something. Interesting, right?

Now for random gifs of One Direction showing examples of gravity! :P
