# Vector and scalar quantities

In physics and mathematics, different types of quantities can be categorized as scalar or vector.

**Scalar quantities**

Scalar quantities are the name given to the quantities that only have magnitude. The quantity can only be described by giving it a magnitude or a specific numerical value. There is no direction associated with scalar quantities. The height of a tower is 50 meters. The tower's height is described as a scalar quantity, as only the magnitude of the tower's height defines it. Suppose it takes 3 hours to complete a lab assignment. The times just need the magnitude of 3 hours to define themselves. Other scalar quantity examples are speed, mass, distance, energy, time, volume, density, temperature, work, distance, and others.

**Vector quantities**

Vector quantities are the quantities that take magnitude and the direction of the quantity. A girl is riding a bike with a velocity of 5 km/h. For defining velocity, we need the magnitude along with the direction. Therefore, velocity is a vector quantity. Some examples of vector quantity are acceleration, displacement, momentum, force, weight, current, and others.
