About Me Scalar sizes In physics, a distinction is made between quantities that are independent of their direction and direction-dependent quantities - do my homework . Such quantities, for which the measurable property is only characterized by an absolute value, are called undirected or scalar quantities. Examples of such scalar quantities are mass, temperature, pressure, density or energy.  In contrast to this, there are also directed quantities such as B. the force or the speed. If you measure z. B. the pressure in a liquid at a certain depth, then one finds: the pressureis always the same at a certain depth, regardless of the direction in which the measuring probe is turned - physic helper . The same applies to the temperature of a body and to other scalar quantities. The quantitative specification of scalar quantities is done by means of a measure and unit, e.g. B. in the following form: ϑ = 25 ° C m = 4.7 kg p = 101 kPa   In the case of scalar quantities, the amounts of the individual quantities can be added. Are z. B. If a mass of 100 g flour and 50 g sugar are poured together, the total mass is obtained by adding : m =m1+m2m = 100 g + 50 g m = 150 g   The same applies to the subtraction of scalar quantities. Vector sizes In physics, a distinction is made between quantities that are dependent on their direction and non-directional quantities - https://domyhomework.club/engineering-homework/ . Such quantities, for which the measurable property is characterized by both a magnitude and a direction, are called directed or vector quantities. Examples of such vector quantities are force, speed or acceleration.  In contrast to this, there are also non-directional quantities such as B. the pressure or the mass. Directed or vector quantities are marked with an arrow above the symbol.
