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 three-halves power of the orbital radius |
