## New words for this packet

Vector - A quantity that has BOTH a size (#) and a direction (left, up, north, etc).

Scalar - A quantity that has ONLY a size (#).

Displacement - Change in position of an object compared to the starting point.

Velocity - A vector quantity found by dividing an objects displacement (often distance is used) by the amount of time taken to travel this distance, includes A DIRECTION.

## Adding Vectors Graphically and Algebraically
