    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,…

  • Physics 9th: Motion | Introduction

    MOTION: INTRODUCTION The most important characteristic of all moving bodies is that they change their position with time. A body is said to be in motion, when it changes its position continuously with respect to a stationary object taken as the standard or reference point. Note: So motion is not absolute, it is relative For…
