**PHY ****101: Mechanics ****(3)**

*Learning Objectives*:

The course will introduce foundations of Newton's laws of mechanics and its application to many particle sytems, rotational motion, non-intertial systems. The course will also introduce the theory of special relativity.

*Course Contents*:

*Kinematics:* Introduction to coordinate systems, polar coordinate system, velocity and acceleration in polar coordinate system.

*Kinetics:* Force, Newtonâ€™s laws of motion, Frames of reference, Momentum, Momentum of system of particles, Conservation laws, Center of mass, Variable mass system, Collision in laboratory and Center of mass system and Scattering.

*Relativity:*** **Axioms of relativity, Lorentz transformation, length contraction, time dilation, relativistic mass energy, Doppler effect.

*Rigid body motion:* Rigid body, Moment of inertia, Rigid body kinematics, Rigid body kinetics, Motion of gyroscope

*Non Inertial Frame:* Physics in the rotating coordinate system, Fictitious force.

*Central force and Motion of planets and satellites*

*Oscillations and Waves:* Small oscillations, damped harmonic oscillation and forced oscillation, Q factor and resonance. Differential equation of one dimensional wave and its solution, reflection and transmission of waves.

*N**ote: Mathematical tools may be introduced as and when required.*
