Q. Define Scalar and Vector quantities with examples:-
Ans:-
Scalar Quantities: Physical quantities which can be denoted only by a number and a specific unit are called Scalar quantities. Scalar quantities do not have any direction and the value of a scalar is called its magnitude.
Scalars are added, subtracted, multiplied and divided by using simple rules of algebra.
Examples of Scalars:
work, energy, volume, time, speed etc
Vector Quantities: Physical quantities which are denoted by a number, a specific unit and also a particular direction are called Vector quantities. Vectors are defined by a magnitude along with a particular direction.
Vectors are added , subtracted, multiplied and divided by using rules of trigonometry and geometry. A vector is represented by capital letters with an arrow above them.
Examples of Vectors:
velocity, force, acceleration, torque, momentum etc
