Conceptual Physics Practice Test Questions and AnSpeed - Answer-How fast an object moves; the distance traveled per unit of time. Instantaneous speed - Answer-The speed at any instant. Average speed - Answer-The total distance traveled divided by the time of travel. Velocity - Answer-An object's speed and direction of motion. Vector quantity - Answer-A quantity that has both magnitude and direction. Scalar quantity - Answer-A quantity that has only a magnitude, not a direction. Accelerat...
