Define: Encompassing direction, and magnitude. Anything involving direction like displacement, position, volume, force, etc. It is described by both direction and magnitude, with speed, velocity, etc. In order to understand motion and forces that occur in two dimension; vectors, and scalers have to be understood.
Example:If you're driving at 30miles/hour and throw a ball out the window behind you at 10 miles/hour what would the speed of the ball be in perspective of the ground. Answer: 20 miles/hour
