1D Kinematics

Uniform Motion and Acceleration

scalar quantity

quantity that only has magnitude (size/amount) but no direction

vector quantity

quantity that has both magnitude (size/amount) and direction

distance

a scalar quantity that describes the amount of a particular unit of measure an object has traveled during an elapsed time period

displacement

vector quantity that measures an objects inital position and its final 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 position (the rate at which an object displaces)

uniform motion

motion with constant velocity

slope of a displacement vs time graph

velocity (/)

uniform acceleration

motion with a constant change in velocity per unit of time

acceleration

vector quantity that refers to the rate at which an object changes its velocity.

slope of a velocity vs time graph

acceleration (/)
