 * Definitions**

Axis-straight like around which rotation takes place. Rotation-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.
 * Circular motion note definitions**

Static friction force-the force that opposes the start of relative motion between the two surfaces in contact. Kenetic friction force-the force exerted on one surface by the other when the surfaces are in relative motion. Electric fields-a vector quantity that relates the force exerted on a charge to the site of the charge.
 * Newton's law of universal gravitation note definitions**

Coulomb's law-the relationship amoung electrical forces, changes, and distances.
 * Coulomb's laws/electric fields note definitions**
