Explanation:
SCALAR QUANTITY = Scalar quantity is defined as the physical quantity with magnitude and no direction.
Scalar quantity is defined as the physical quantity with magnitude and no direction.Some physical quantities can be described just by their numerical value (with their respective units) without directions (they don’t have any direction). The addition of these physical quantities follows the simple rules of the algebra. Here, only their magnitudes are added.
VECTOR QUANTITY = A vector quantity is defined as the physical quantity that has both direction as well as magnitude.
A vector quantity is defined as the physical quantity that has both direction as well as magnitude.A vector with the value of magnitude equal to one and direction is called unit vector represented by a lowercase alphabet with a “hat” circumflex. That is “û“.
