Gravity By: Lauren Hinshaw

Universal Gravity Universal gravity is the force of gravity on every object to an extent. Example: The earth has a bigger gravitational pull on us, because the earth has a greater mass. We have a smaller mass compared to the earth, so our gravitational pull is smaller to the earth. Question: Does someone who is bigger than me like a basketball player, would he have a greater gravitational pull?

Weight Weight is the amount of gravity upon an object. Example: If I weigh 120 lbs. then that means that there is 120 Ibs. pressuring on my body. Gravity is measured in Newtons.

Mass Mass is the amount matter in an object. Mass is measured in SI unit of mass and kilograms. 1 kilogram = about 400 pennies.

9.8m/s2 9.8m/s means that when an object is falling, it's velocity increases 9.8m/s in one second. So if you fell for 9.8m/s in one second, you would fall 19.6m/s in two seconds! And so on. I've realized that its kind of like layers of blankets. The more the blankets the heavier it will be.

Horizontal motion and Vertical motion If you throw a ball horizontally at the same time as dropping a ball vertically, they will land at the same time. Why? The gravity is still forcing the horizontally thrown ball towards the ground. So it will land at the same time. If you jump across a big gap( if its big enough) you will fall a little forward and straight down. You will eventually run out of horizontal motion.
