Question

1. matching: for the list of terms to the left, identify which definition listed on the right best fits the term. write the letter of the definition next to the word. each definition is used only once.

terms:
____ displacement
____ distance
____ origin
____ position
____ scalar
____ starting position
____ vector
____ velocity
definitions:
a. how fast an objects position changes; or the slope of a position vs. time graph.
b. a quantity (number) that is fully described by a magnitude only.
c. a fixed reference point.
d. the measurement of how far from the origin in a certain direction an object is; location.
e. a quantity (number) that is fully described by both a magnitude and direction; represented on a motion map by an arrow.
f. how far you travel, counting the steps.
g. how far you are out of place; the change in position.
h. the initial location; intercept on a position vs. time graph.

Explanation:

• Displacement: It is about the change in position, which matches with "How far you are out of place; the change in position" (g).
• Distance: It is the total path covered (counting steps), so it matches with "How far you travel, counting the steps" (f).
• Origin: A fixed reference point (c).
• Position: It is the location with respect to the origin, so "The measurement of how far from the origin in a certain direction an object is; location" (d).
• Scalar: A quantity with magnitude only (b).
• Starting position: The initial location (h).
• Vector: A quantity with magnitude and direction (e).
• Velocity: How fast position changes (slope of position - time graph) (a).

Answer:

Displacement - g, Distance - f, Origin - c, Position - d, Scalar - b, Starting position - h, Vector - e, Velocity - a
