Atmospheric motion vectors (AMVs) are derived estimates of wind velocity obtained by tracking the motion of identifiable features, most commonly cloud elements, in sequential satellite imagery. The ...

Today we continue on our journey of understanding motion, direction, and velocity. Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of ...

Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations. Motion - ...

Scalar quantities have only magnitude (size). For example, 11 m and 15 m s-1 are both scalar quantities.
