2.01A  I know the difference between position, distance, and displacement (change in position) and I can determine each.
Can You...
 Define and differentiate the following terms
Vector:
Physical quantity which has a value (magnitude) and a direction. Examples:
Scalar:Physical quantity which has a value, but NO DIRECTION. Examples:


Position:
Position is an object's location with respect to a particular coordinate system.
 I would think of this as an address. It tells you where something is, but not how to get there.
Distance:
Distance is the magnitude (length) of the displacement vector
Displacement (Change in Position):
Displacement is a vector that starts from an object's initial position and ends at its final position.
Speed:
How much distance is travelled in a certain amount of time.
Velocity:
How much your position changes in a certain amount of time.
Acceleration:
How much velocity changes in a certain amount of time.
 If velocity increases (positive acceleration), it becomes more positive. If an object has a positive velocity, it would speed up to make the velocity more positive. But if velocity is negative, it would have to slow down to make the velocity more positive.
 If velocity decreases (negative acceleration), it becomes more negative. If an object has a positive velocity, it would slow down to make the velocity more negative. But if velocity is negative, it would have to speed up to make the velocity more negative.
