# Position, Velocity, Acceleration

## What is Position?

position (s): the location of an object/subject at a given moment in time

s: think of this as your location on a number line (shown as the red circle below)

displacement: the difference in location from one time to another

Δs: think of this as the difference between your first and second location on a number line

## What is Velocity?

velocity: the change in position with respect to time; gives an object’s speed and direction of its motion

## What is Acceleration?

acceleration: the change in velocity with respect to time

## What are Vectors?

vectors: a quantity having direction and magnitude; aids in determining the position of one point in relative space
