Acceleration is a vector because it has a magnitude and a direction (Accelerating at a rate of 5 Miles Per Hour North). Speed is a scalar because it only has a magnitude (35 Miles Per Hour) . Velocity is the derivative of the acceleration and is also a vector (35 miles per hour North). Adam Â· 5 years ago. Thumbs up.
The speed of an object is a scalar (e.g. 180 km/h), while its velocity is not (i.e. 180 km/h north). Other examples of scalar quantities in Newtonian mechanics include electric charge and charge density. An example of a pseudoscalar is the scalar triple product (see vector), and thus the signed volume.or example, the charge density at a point in a medium, which is a scalar in classical physics, must be combined with the local current density (a 3-vector) to comprise a relativistic 4-vector.
