toc =Definitions= Circular Motion-The movement of an object at a constant speed around a circle with fixed radius. Axis-Straight line around which rotation takes place. Rotation- Object turns around in an __internal__ axis. Revolution- Object turns around an __external__ axis. Linear Speed- Distance time. Tangential Speed- Speed along a circular path. Rotational Speed-Number of rotations per unit of time. Centripetal Force- Force that causes an object to follow a circular path.
 * Circular Motion**

Gravity- A constant force exerted by objects that have a mass. Weight- The pull of gravity. Newton- The unit of force in which is measured by weight. Law of gravitation-Every object in the universe attracts every other object. Gravitational Attraction- The force of attraction between objects. Law of universal gravitation- States that gravitation forces were responsible for the acceleration of objects on the moon and on the earth.
 * Gravity and Weight**

Static friction force-Exerted on one surface by the other when there is no relative motion between two surfaces. Kinetic friction force- Is the force exerted on one surface by the other when the surfaces are in relative motion.
 * Friction**

Coulomb's Law- The relationship among electrical forces, charges, and distance. Electric Fields- A vector quantity that relates the force exerted on a charge to the size of the charge. Electric Potential Difference- Causes charges to move. Grounding- Touching a body to earth to eliminate excess charge. Electric Current- Flow of charged particles.
 * Coulomb's Law/Electric Fields**

=**Explanation**= The formula that explains Centripetal force is as follows: To convert pounds to newtons you must multiply the number of pounds by 4.45, since 1 pound equals 4.45 newtons.

The formula that explains Newton'a Law of gravity is as follows: The formula that explains Universal Gravitation is as follows:

The formula that explains Coulomb's Law is as follows:
