Physics 9th: Motion | Scalar and Vector Quantities
9th Physics | Motion | Scalar and Vector Quantities Scalar Quantities Those physical quantities having magnitude but no direction are called scalar quantities. For example Mass, Length (Distance), Time, Volume, Density, temperature and humidity etc. Vector Quantities Those physical quantities that have magnitude as well as direction are called vector quantities. For example displacement, velocity,…
