1. Gravity
The Forces in Creation

2. 4 Forces of Creation 1. Gravity Attractive force between 2 objects
weakest force
equal strength between 2 objects from opposite directions

3. 4 Forces of Creation 2. Electromagnetic
between particles w/ electric charge
can be attractive or repulsive
likes repel; opposites attract

4. 4 Forces of Creation 3. Weak Force 4. Strong Force
govern radioactive processes in atoms
holds the center of the atom, the nucleus, together
the strongest force
small range

5. 3 Basic principles of Gravity from the Universal Law of Gravitation
1. All objects with mass are attracted to one another by the gravitational force
2. The gravitational force between 2 masses is directly proportional to the mass of each object.
(If you increase the mass of 1 object, then gravitational attraction increases, too.)
3. The gravitational force between 2 masses is inversely proportional to the square of the distance between those 2 objects.
If Distance big, force small.
If distance small, force big.

6. Circular Motion Centripetal Force
(Def.) force that makes an object move in a circle. It is perpendicular to the velocity of the object, toward the center of the circle
Circular motion requires centripetal force
The larger the centripetal force, the faster an object travels in a circle of a given size
At a given speed, the larger the centripetal force, the smaller the circle.
