| mechanics | study of motion of objects |
| kinematics | science of describing the motion of objects using words, diagrams, numbers, graphs, and equations |
| scalars | quantities that are fully described by a magnitude or a numerical value alone |
| vectors | quantities that are fully described by both a magnitude and a direction |
| distance | scalar quantity that refers to "how much ground an object has covered" during its motion. |
| displacement | a vector quantity that refers to "how far out of place an object is": it is the object's overall change in position. |
| speed | scalar quantity that refers to "how fast an object is moving." |
| velocity | vector quantity that refers to "the rate at which an object changes its position." |
| instantaneous speed | the speed at any given instant in time |
| average speed | the average of all instantaneous speeds |
| acceleration | a vector quantity that is defined as the rate at which an object changes its velocity |
| constant acceleration | the velocity is changing by a constant amount each second. |
