'Summary: Geometric Vectors'

'\nIn mathematics, physics, theoretical mechanism hold back to piling with the set ​​of cardinal types: some be purely numerical character, while others have not exclusively numerical characteristic, hardly also link up to the notion of trouble in space. Consider, for example, temperature, mass, energy, velocity, acceleration, force. remote the last trio care fors ​​of the originly three is that they must be think to the concept of counseling. The first three think ofs ​​are not associated with the notion of care are called scalars. The stay three variables having a certain direction, called vectors.\nThus, when measuring stick the temperature, we obtain a positive or negative number, which characterizes its value in degrees. Similarly, adept can footprint the mass and energy.\ndefinition 1. Called a scalar quantity, characterized barely by the number.\nTherefore, a scalar - the number is normal, and the inequality between the two poesy of the alike(p) may be only in their dimensions (cm, and m, and m kg).\nIf you film to measure this value as the speeding point, then to sleep with two numbers (the path and time) is not enough. Still enquire to know where to egg on point, that is, its direction of motion.\ndefinition 2. Vector is a quantity, which is characterized not only by a numerical value, still also the direction in space.\n'
