  • Physics 9th: Motion | Distance and Displacement

    9th Physics | Motion | Distance and Displacement Distance (a)    The distance travelled by a body is the actual length of the path covered by a moving body irrespective of the direction in which the body travels (b)    It is a scalar quantity therefore it has only magnitude Displacement When a body moves from one point to…

  • 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,…
