Single- and multi-axis models of accelerometer are available to detect magnitude and direction of the proper acceleration, as a vector quantity, and can be used to sense orientation (because direction of weight changes), coordinate acceleration, vibration, shock, and falling in a resistive medium (a case where the proper acceleration changes, since it starts at zero, then increases). A vector with a direction of 270 degrees is a vector that has been rotated 270 degrees in a counterclockwise direction relative to due east. This is one of the most common conventions for the direction of a vector and will be utilized throughout this unit.
Many common physical quantities are often vectors or scalars. Vectors are akin to arrows and consist of a positive magnitude (length) and importantly a direction. on the other hand scalars are just numerical values sometimes possibly negative. Note that although vector magnitudes are positive or perhaps zero the components of vectors can of course be negative indicating vector directed contrary to the coordinate or reference direction. Examples of vectors: force, velocity, acceleration, displacement, weight, magnetic field, etc. Examples of scalars: mass, temperature, speed, distance, energy, voltage, electric charge, pressure within a fluid, etc. While scalars can be added directly like numbers (e.g. 5 kJ of work plus 6kJ equals 11kJ ; or 9 volt plus minus 3 volt gives 6 volt: +9v plus -3v gives +6v ), vectors are slightly more complicated to add or subtract, although collinear vectors are easy and behave like adding numbers which may be negative. See below several ways to tackle vector addition and subtraction.
