The term acceleration can refer to a scalar acceleration or an acceleration vector. So far, we have only met scalar acceleration, e.g. 5 m/s 2. Vector acceleration is a scalar acceleration and a direction, e.g. 5 m/s 2 to the right.Treat acceleration as a vector when there is another vector quantity, such as velocity or force, involved. Forces need a size and direction, e.g. 300 N to the left.Momentum is equal to mass x velocity.o far, we have only met scalar acceleration, e.g. 5 m/s 2.

Both the odometer and speedometer are scalar because a vector measurement needs a magnitude and direction. If you, for example, combined a compass and a odometer/speedometer, you'd have a vector.t's a rather puzzling idea, but area can be either a scalar or vector quantity. Usually area is a scalar quantity. E.g. the area of my house is 2000 square feet. In more adva â¦ nced calculus courses you'll run into area vectors.
