motion diagram

a series of images of a moving object that records its position after equal time intervals

origin

point at which the variables have the value zero

scalar quantity

quantity that tells you only the magnitude of something

vector quantity

quantity that tells you magnitude & direction of something

displacement

distance & direction b/w 2 positions/points

distance

length or size of displacement vector b/w 2 positions

resultant vector

equal to the sum of 2 or more vectors; aka displacement vector

vector resolution

process of breaking a vector into its components

components

magnitude & sign of component vectors

average speed

ratio of the total distance traveled to the time interval
