  # Vectors

A quantity which is completely specified by a number with an appropriate unit is called a scalar. A scalar has only magnitude but no direction. Some scalars like volume and mass are always positive. Other scalars like temperature and electric charge can be either positive or negative. A quantity which is completely specified by a number with an appropriate unit and direction is called a vector. Thus, a vector has both magnitude and direction. Examples of vectors are velocity, acceleration, force, momentum, torque etc. We have video lectures on Addition of Vectors, Subtraction of Vectors, Resolution of Vectors, Product of Vectors and other aspects of vector with suitable examples and problems.
