The focus of the lecture is simple harmonic motion. Professor Shankar gives several examples of physical systems, such as a mass M attached to a spring, and explains what happens when such systems are disturbed. Amplitude, frequency and period of simple harmonic motion are also defined in the course of the lecture. Several problems are solved in order to demonstrate various cases of oscillation.

Google has proven that if you build it, they will come, and their mass of tools to keep users logged in has been the crux of their success. Vice President of Search Products & User Experience Marissa Mayer elaborates on this strategy, pointing out that money - and advertisers - will always follow consumers. Focus on building sticky media that draws in a wide audience, and the method to its monetization will follow.

Concepts covered in this lecture begin with the restoring force of a spring (Hooke's Law) which leads to an equation of motion that is characteristic of a simple harmonic oscillator (SHO). Using the small angle approximation, a similar expression is reached for a pendulum. To demonstrate that the period is independent of the mass of the bob, Professor Lewin places himself at the end of the 5 meter long cable and measures the period.

The discussion of four-vector in relativity continues but this time the focus is on the energy-momentum of a particle. The invariance of the energy-momentum four-vector is due to the fact that rest mass of a particle is invariant under coordinate transformations.

In this lecture Professor Lewin covers elastic and inelastic collisions, including a discussion on center of mass and internal inergy. He concludes with a Newton's Cradle demonstration, soliciting an analytical proof of his demo showing a lineup of colliding balls.
