Gravity By: Lauren Hinshaw

Universal GravityUniversal 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.
