# Mass is a _____ quantity. (a) scalar (b) vector (c) tensor (d) None of these

Correct option: (a) scalar

Mass is a scalar quantity. The mass of a body is a scalar quantity. The mass has only magnitude, not direction. If we consider the weight, it is the force experienced by the object due to its mass. Hence, weight has both magnitude and direction.

### Scalar quantity

A scalar quantity is defined as the physical quantity with magnitude and no direction.  In other terms, a scalar is a measure of quantity. For example, if I say that the height of a tower is 15 meters, then the tower’s height is a scalar quantity as it needs only the magnitude of height to define itself.
