Question

2 multiple choice 0.5 points reading: which statement best describes average velocity? it equals displacement / time interval and includes direction (sign). it equals total distance / time interval and is always positive. it is the area under a position - time graph. it is the same as speed, just written with an arrow.

Explanation:

Average velocity is a vector quantity, meaning it has both magnitude and direction. It is calculated as the displacement (a vector measuring change in position, including direction) divided by the time interval.

• The second option describes average speed (a scalar using total distance, always positive), not velocity.
• The area under a position-time graph represents displacement, not velocity.
• Velocity is not just speed with an arrow; speed is the magnitude of velocity, and velocity includes directional information that speed does not.

Answer:

A. It equals displacement / time interval and includes direction (sign).
