|
What is distance (d)? |
A scalar quantity that describe the length of a path between two points or locations. |
|
|
What is position (d with an arrow)? |
A vector quantity that describes a specific point relative to a reference point. |
|
|

The difference between the final and initial times. |
|
|
What is displacement? |
Describes the straigh-line distance and directions from one point to another ex. 5m (E) |
|
|
What is uniform motion? |
objects that travel in equal displacements in equal time intervals are in uniform motion |
|
|
What is a slope on a graph? |
A slope indicates the motion of the object |
|
|
What is speed (v) |
The distance an object travels during a given time interval divided by the time interval (Scalar quantity) |
|
|
What is velocity (v with an arrow) |
The displacement of an object during a time interval divided by the time interval (vector quantity) |
|
|
What is average velocity? (Vav) |
The rate of change in position for a time interval |
|
|
