Term

Definition
the motion of an object traveling at a constant (uniform) speed on a circular path 


Term

Definition
the time required to travel once around the circle; the time required to make one complete revolution 


Term
Does the definition of uniform circular motion state that the direction of the velocity vector stays constant? 

Definition


Term
The acceleration in uniform circular motion is called _____ because it points toward the center of the circle 

Definition


Term
Since the word _____ means "moving toward a center", the acceleration in uniform circular motion is called centripetal acceleration 

Definition


Term
What is the direction of centripetal acceleration? 

Definition
the centripetal acceleration vector always points toward the center of the circle & continually changes direction as the object moves 


Term
centripetal force (vector Fc) 

Definition
the net force causing the centripetal acceleration; points in the same direction as the acceleration (toward the center of the circle) 


Term
Is the centripetal force always one force? 

Definition
no! (it can be the net sum of many forces) 


Term
For a given orbit, does mass matter for orbital speed of a satellite? 

Definition


Term

Definition
the fact that the period is proportional to the threehalves power of the orbital radius
