Scalar quantity - Study guides, Class notes & Summaries

Conceptual Physics Practice Test Questions and Answers Speed - 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 dir...

Scalar - ANS-quantities with only magnitude such as speed, distance, time and mass. Vector - ANS-quantities with a magnitude and direction e.g. acceleration, force momentum and weight. A vector quantity can be represented as an arrow, the size representing the magnitude and the direction, the direction.
