Question

LRecall that an object's average velocity includes a value (also called magnitude) and a direction.

This means that speed and velocity can never be the same because speed doesn't include direction. However, it is possible for the speed to be equal to the magnitude of the average velocity. Under what circumstance will an object's average speed have the same value as the magnitude of its average velocity?

• an object's average speed is always equal to the magnitude of its average velocity
• when the object travels in a circular path
• when the object returns to its starting position
• when the object travels in a straight-line path

The correct answer is when the object travels in a straight-line path. When an object moves in a straight line, its average velocity and average speed will have the same magnitude because there is only one direction involved. However, if the object changes direction or moves in a curved path, the average velocity will have a different magnitude than the average speed.
