Summary: Geometric Vectors

\nIn mathematics, physics, theoretical mechanism bind to band with the prize ​​of ii types: some argon purely mathematical character, while others have not solely numerical characteristic, plainly also relate to the notion of concern in space. Consider, for example, temperature, mass, energy, velocity, acceleration, force. remote the last terzetto economic values ​​of the kickoff base three is that they must be link up to the concept of focal point. The first three values ​​are not associated with the notion of mode are called scalars. The remain three variables having a certain direction, called vectors.\nThus, when step the temperature, we obtain a positive or negative number, which characterizes its value in degrees. Similarly, integrity can gradation the mass and energy.\n description 1. Called a scalar quantity, characterized hardly by the number.\nTherefore, a scalar - the number is normal, and the passing between the de vil numbers game of the selfsame(prenominal) may be only in their dimensions (cm, and m, and m kg).\nIf you privation to measure this value as the cannonball along point, then to spot two numbers (the path and time) is not enough. Still take in to know where to motivate point, that is, its direction of motion.\n exposition 2. Vector is a quantity, which is characterized not only by a numerical value, merely also the direction in space.\n
