Vectors


In this unit of physics, we have been discussing vectors. A vector is a quantity that has both direction and magnitude. Magnitude pretty much means amount of something. So a vector quantity is described by its amount and the direction of that amount. Some vector quantities are velocity and acceleration. Velocity is a vector quantity because it involves a speed along with a direction in which the object is moving. Acceleration is a vector quantity because that same object can be increasing or decreasing velocity in the same or a different direction. The picture below is of me skating down a ramp in the parking lot. This relates to vectors, because I am accelerating at a certain rate in the direction of the lower level.
