On successful completion of this practical course, the student will be able to;

  • Perform experiments on Properties of matter such as the determination of moduli of elasticity , Young’s modulus, Rigidity modulus of certain materials; Surface tension of water , Coefficient of viscosity of a liquid , Moment of inertia of some regular bodies by different methods and compare the experimental values with the standard values.
  • Know how to determine the acceleration due to gravity at a place using Compound pendulum and Simple
  • Notice the difference between flat resonance and sharp resonance in case of volume resonator and sonometer experiments
  • Verify the laws of transverse vibrations in a stretched string using sonometer and comment on the relation between frequency, length and tension of a stretched string under
  • Demonstrate the formation of stationary waves on a string in Melde’s string experiment.
  • Observe the motion of coupled oscillators and normal

  • Assignments (in writing and doing forms on the aspects of syllabus content and outside the syllabus content. Shall be individual and challenging)
  • Student seminars (on topics of the syllabus and related aspects (individual activity)
  • Quiz (on topics where the content can be compiled by smaller aspects and data (Individuals or groups as teams)
  • Field studies (individual observations and recordings as per syllabus content and related areas (Individual or team activity)
  • Study projects (by very small groups of students on selected local real-time problems pertaining to syllabus or related areas. The individual participation and contribution of students shall be ensured (team activity)


  • Group Discussion
