My Inquiry Project will be about GRAVITY!! , to start off, I’ll explain what Gravity is. Gravity is what pulls you to the ground every time you jump. Without Gravity, you’d float up and pass Earth’s Atmosphere. Any object that has mass is affected by gravity. Gravity acts like a magnet which pulls objects, with mass, to the ground. What causes Gravity is unknown.

 

Today, I learned that sometimes people confuse mass with weight, when really, weight is the result of mass.

Today I learned what mass was made of and what it does. Mass is made of the stuff matter is made of, Molecules. Molecules are a bond of Atoms together, and Atoms are made of the three subatomic particles: Protons, Neutrons, and Electrons. Mass is also the amount of stuff in an object. Mass is measured in KG (Kilograms).

Today I did more research and Found out that there was a Scientist (I think) named Galileo Galilei, who wanted to figure out which would come down first, a ten pound ball or a five pound ball. Both balls came down at the same time. Gravity works the same on all objects, unless wind, or anything else, comes in the way.

 

I also found out how strong Gravity. Just imagine Gravity pulling on everything and not letting it go, not even light! This is the start of a black hole. The gravity in the black hole pulls everything into the center which may be small as a single atom. This makes a black hole not visible! There are at least approximately more than a million black holes in the Galaxy!

So how do Astronauts float in space if the pull of Gravity is so strong? Well, the Astronauts are still being pulled by Earth’s Gravity, just the same as the rest of us.

 

I also learned more facts on Sir Isaac Newton, who is known-credited for explaining Gravity. Like the fact that he published all his ideas in a book in 1687, and his famous three laws of motion!

 

What is matter?

Matter is what is needed to make/cause mass. Matter is made of molecules, which are made with Atoms. There are 5 states of matter: Liquid, Solid, plasmas, Gases (Clouds and stuff), and be condensates.

The Inquiry Fair is going to come up soon, so I have to get more facts, and start formatting my poster on Gravity. I found out a fact I should have known, Gravity keeps planets in orbit.

Just to sum it all up, Gravity has a gravitational pull which only works with objects that have mass, the pull is stronger or weaker depending on the amount of Mass the object has. Gravity is a force of attraction. You can exert a gravitational pull on the people around you, but it won’t be super strong.
