GRAPHING:

A). view the link and explain the speed of the object.  Notes:   Circular motion is the movement of an object at a constant speed around a circle with a fixed axis.  Linear speed = distance/time, rotational speed = number of rotations per unit time.  Tangenial speed = speed along a circle. – V= RW  Centripetal force causes an object to follow a circular path.  ~ Fnet = Mv(squared)/R~  Centripetal acceleration = Ac =V(squared)/R  Revolutions = distance / circumference  Newton and gravity  Newton believed that gravitational force were responsible for acceleration on earth and on the moon. He concluded that all objects in the universe have gravitational attraction to one another.  Mass is different than weight depending on gravity.  1M-O = 1F = O-1M  1M-O = 2F = O-2M  2M-O = 4F = O-2M  EFFECTOF DISTANCE ON GRAVITY  1D 2D  O-O O-O  F 1/4F  UNIVERSAL GRAITATION FORMULA  F = Gm1m2/ D(squared)
