Physical Quantity -

The quantities expressed in terms of laws of physics are called physical quantity.

For example - Mass of an object, Length, Force, Speed, Distance, Displacement, Momentum, Electric Current.

These are of two types :-

1. SCALARS - Those physical quantities which have magnitude only and whose direction is not taken into the consideration are called Scalars.

Example : Mass, Temperature, Density, Volume, Electric Current, Work etc.

2. VECTORS - Those physical quantities which have both magnitude and direction and which are represented by the directed line segment obeying the triangle law of vectors or parallelogram law of vectors are called Vectors.

Example : Displacement, Linear Momentum, Angular Velocity, Torque, Magnetic Field Intensity, Electric displacement, Current density etc.
