Newton’s Law of Universal Gravitation

Newton's law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

aka. Everything attracts to each other in equal force.

Formula

{The variables of the formula

Breaking it up

Force of attraction Newtons

F

Gravitational constant

G

Mass of the first object Kilograms

m1

Mass of the second object Kilograms

m2

Distance between the two objects meters

r

Some visual representations

Written Out Formula

Make sure to covert into corresponding unit

The gravitational constant is equivalent to

G/1… fraction so it would go on top to solve

…plug into calculator correct … Keep track of your time

Do the questions as quick as possible while still getting them correct

You’ll do great
