Scalar quantity is a quantity only tell the size be integrity, but no direction. Finding the results of quantitative and mathematical principles, Kela, using, for example, such as length, scalar, energy, time, temperature, pressure, acceleration. Speed.For example, the steel has a length of 2 meters, water temperature 50 C, etc. However, although scalar quantity is the quantity has no direction. But it can be changed in one direction. For example, the temperature.When the points are being considered to move him to a heat source. The direction of the scalar quantity change the most, that can be obtained from the gradient of the scalar quantity
