A system used to describe motion that gives the zero point location of the variable being studied and the direction in which the values of the variable increase
A change in position having both magnitude and direction; is equal to the final position minus the initial position
Select the correct definition:
Instantaneous Position
The ratio of an object's change in position to the time interval during which the change occurred; for uniform motion, it is the slope of the object's position-time graph
A change in position having both magnitude and direction; is equal to the final position minus the initial position
