Physics

2. quantity / A quantity that has magnitude and acts in a particular direction is described as a vector.
3. / Is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.
6. / Is a scalar quantity that refers to "how much ground an object has covered" during its motion.
7. / Are quantities that are fully described by both a magnitude and a direction.
8. / Are quantities that are fully described by a magnitude (or numerical value) alone.
10. / Is a vector quantity that is defined as the rate at which an object changes its velocity.
12. Speed / The average of all instantaneous speeds; found simply by a distance/time ratio.
13. / Is the phenomenon in which an object changes its position over time.

1. / Is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
4. Speed / The speed at any given instant in time.
5. / The study of the motion of objects.
7. quantity / A quantity that has magnitude but no particular direction is described as scalar.
9. / Is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. Kinematics is a branch of mechanics.
11. / Is a vector quantity that refers to "the rate at which an object changes its position."
