Scalar and vector quantities

Om Prakash Mishra
24/09/2018 1 0

Scalar quantity: Those quantities which have the only magnitude but no direction are called scalar quantities. For instance mass, time, length, distance.

Vector quantity: Those quantities which have both, as well as direction, are called vector quantities. For instance Force, weight, displacement, acceleration.

Scalar quantities are Sony added and multiplied by the law of algebra, but vectors are added and multiplied by special law of vectors.

Note: Note electric current though has direction but does not obey the law of addition of vectors, so it is also a scalar quantity.
