In physics, scalars (or scalar quantities) are physical quantities that are unaffected by changes to a vector space basis (i.e., a coordinate system transformation). Scalars are often accompanied by units of measurement, as in "10 cm". Examples of scalar quantities are mass, distance, charge, volume, time, speed, … See more A scalar in physics is also a scalar in mathematics, as an element of a mathematical field used to define a vector space. For example, the magnitude (or length) of an electric field vector is calculated as the See more An example of a scalar quantity is temperature: the temperature at a given point is a single number. Velocity, on the other hand, is a vector quantity.
