1. Newton’s law of Universal Gravitation

2. Newton’s Law of Universal Gravitation
Any two objects attract each other with a gravitational force, proportional to the product of their masses and inversely proportional to the square of the distance between them.
The force acts in the direction of the line connecting the centers of the masses.

4. Why does the moon not fall straight down onto the earth?

5. Henry Cavendish’s experiment determined the proportionality constant G in 1798.

6. Law of Universal Gravitation

7. Write in your own words What Newton’s law of Universal Gravitation force is and label all parts of the formula.

8. Newton's law of gravitation  
The principle that expresses the force of gravitational attraction between two bodies as a function of their mass and their distance.
Expressed mathematically, F = G m1m2/r 2where F is the force in Newtons, m 1 and m 2 are the masses of the bodies in kilograms, G is the gravitational constant, and r is the distance between the center of the bodies in meters.
Newton's Principle of Gravitation is an example of an inverse square law.
