Chapter 2: Motion in One Dimension Glossary

the rate at which velocity changes

distance traveled divided by time during which motion occurs

displacement divided by time over which displacement occurs

the variable that changes as the independent variable changes

the change in position of an object against a fixed axis

the length of the path actually traveled between an initial and a final position

the variable, usually along the horizontal axis of a graph, that does not change based on human or experimental action; in physics this is usually time

speed at a specific instant in time

velocity at a specific instant in time

the study of motion without considering its causes
