VECTORS Physical quantities are classified in to two categories i) Scalar quantities ii)Vector quantities1. Scalar quantities or Scalars :The physical quantities which have magnitude but no direction are called   scalar quantities or scalars. Ex:Length,mass,time,area,volume,speed,energy,work,temperature etc2.Vector quantities or Vectors:The physical quantities which posses magnitude as well as direction are called Vector quantities or Vectors. Ex:Displacement,velocity,acceleration,momentum,force etcGeometrical […]
