Question

What is meant by scales and vectors

Answer 1

Answer:

When talking about vectors, a real number is sometimes called a scalar. Scaling a geometrical vector means keeping its orientation the same but changing its length by a scale factor. It is like changing the scale of a picture; the objects expand or shrink, but the directions remain the same.

Answer 2

Scalar Quantities: The physical quantities which are specified with the magnitude or size alone are scalar quantities. For example, length, speed, work, mass, density, etc.

Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction. For example, displacement, force, torque, momentum, acceleration, velocity, etc.
