1. A quantity that has magnitude but no particular direction is described as scalar.
A quantity that has magnitude and acts in a particular direction is described as vector.
2. A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight.
3. A vector is a quantity that has both a magnitude and a direction. Vector quantities are important in the study of motion. Some examples of vector quantities include force, velocity, acceleration, displacement, and momentum.
i hope it can help. ;)
