Unit 1 Frames of reference. (8 Hours)

 Inertial frame of reference-Galilean transformation equations and Invariance- Non inertial frames- Centrifugal force and Coriolis force

 Unit 2. Conservation of Energy and Momentum (14 Hours )

Conservation of energy of a particle –Energy function- Potential energy curve- Conservative and Non conservative forces- Conservation of Linear momentum-Center of mass frame of referenceRockets- motion under central force- Conservation of angular momentum (Illustrate suitable example) 

Unit 3 Relativity( 12 Hours )

Postulates of special theory-Michelson Morley experiment-Lorentz transformation equationsLength contraction-Time dilation- Twin paradox- variation of mass with velocity-Mass energy relation- momentum energy relation

 Unit 4 Oscillation and Waves (10 Hours )

Simple harmonic motion (Elementary idea) - equation –examples like oscillation of simple pendulum, loaded spring-An harmonic oscillator-Damped harmonic oscillator. Wave motionEquation for plane progressive wave-Energy density- Pressure variations of plane waves.
