circular motion notes:the movement of an object at constant speed around a circle with fixed radius

axis:straight line wich rotation takes place

rotation-object turns around internal axis

revolution-object turns around extrnal object rotational sped

linear speed-d/t tangential speed to go around. rotational speed-number of rotation per units. tangential=radial dist. times the rotational speed

centripetal force-force that causes an object to follow a circular path. Fnet=MVsquared/r

newtons law of universal gravitation 2 objects in the universe exert gravitational attraction on each other.
 * the law applies to all objects.
 * distance increases the less gravitational pull.


 * distance decreases the more gravitational pull.
