Question

which statement is true about velocity?
does not have a measurement of speed or direction.
must have a measurement of speed.
must have only direction.
must have a measurement of speed and direction.

Explanation:

To determine the true statement about velocity, we recall the definition of velocity in physics: velocity is a vector quantity, which means it has both magnitude (speed) and direction.

• The green option is incorrect because velocity does have speed (magnitude) and direction.
• The purple option is incorrect as it only mentions speed (magnitude) but ignores direction, and velocity needs both.
• The orange option is incorrect because velocity needs both speed (magnitude) and direction, not just direction.
• The cyan option is correct because velocity, being a vector, must have a measurement of speed (magnitude) and direction.

Answer:

D. Must have a measurement of speed and direction. (Assuming the cyan option is labeled D; if the labels are A - D with A: green, B: purple, C: orange, D: cyan, then the correct answer is D. Must have a measurement of speed and direction.)
