Transcription: Physicists have found that the direction of motion is as important as the speed. They use the word velocity to represent both speed and direction. If Ringo travels in the negative direction by backing up or turning around, we say he has negative velocity. You can think of velocity as an arrow pointing in the direction of motion with its length proportional to the speed. More generally, If Ringo drives in any direction, we represent his velocity by an arrow. For example, V equals 32 meters per second at 28 degrees east of north.
