Astronomy Lesson One! Enjoy.

1. Newton’s Law of
Gravitation
{ Astronomy: Lesson 1
By: Chelsea Shi

2.  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.

3. Formula

4. Breaking it up
{ The variables of the formula

5.  Force of attraction
 Newtons
F

6. G

7.  Mass of the first object
 Kilograms
m
1

8.  Mass of the second object
 Kilograms
m
2

9.  Distance between the two objects
 meters
r

10. Written Out Formula

11.  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 
