Scalar quantities explain one-dimensional quantities. Scalar-and-vector-quantities-4.5.1.1-solutions. If v is a nonzero vector and c is a nonzero scalar, we define the product of c and v, denoted c v, to be the vector whose length is c times the length of v and whose direction is the same as that of v if c > 0 and opposite to that of v of c < 0. Examples of vector quantities: force has a value and a direction. What is the difference between speed and velocity? Expert Answer: Quantities which have only magnitude and no direction are called scalar quantities: Info. Author: Created by danielburke409. These quantities do not obey the law of vector addition. For example: displacement, velocity, acceleration etc. electric charge has only a value, no direction. vector Start 2.1 Addition and Subtraction of Vectors The study of mechanics involves the measurement of physical quantities such as position, mass, velocity, acceleration, force, moment of inertia, time, and angular speed. Two or more than two scalar quantities measured in the same system of units are equal if they have the same magnitude and sign. Presentation and accompanying lesson notes on scalars and vectors. A scalar quantity is different from a vector quantity in terms of direction.
