In this video Professor Lewin does a great job of introducing some of the principles of rotation. He does several demonstrations of artificial gravity with a centrifuge and then with a bucket and rope. The video provides a great introduction to the mechanics of rotation.

In this video professor Lewin does a great job of debunking common misconceptions of gravity (like the idea that heavy objects fall faster) with fun and intuitive experiments, It is a great introduction to physics concerning gravity.

In this video Professor Lewin thoroughly describes some of the simpler physics concepts of 1-d motion, If you have taken calculus you will probably be familiar with these concepts but it is still a good introduction to the format of Professor Lewin's videos, if you intend to watch more of them in the future.

In this video Professor Lewin discuses the principle of buoyancy. This video would probably be a good place to start for anyone interested in buoyancy. He had an interesting demonstration at the end when he took a pingpong ball and suspended it in an air stream showing that the pressure was lower in the places where the velocity was higher.

In this video he discusses gases pascal's principle and in-compressible fluids. He has some good demonstrations of these principles, such as shooting a paint can filled with water to demonstrate that water is (almost) in-compressible.

In this video Professor Lewin does some awesome things, he discuses dimensional analysis in a way that makes dimensional analysis feel simple and intuitive. He explains some of its advantages and some of its weaknesses. This video was also generally a good introduction to the application of units, and scaling arguments.

This videos discussed the differences between real images and virtual images, as well as the differences between diffuse and specular reflections, and even explains refraction and its applications in optics. It also walks you through using focus point definitions of curves to determine what type of image and where it will be or appear to be. Near the end it even shows you some actual calculations about the exact position of images.

This video discussed the difference between absolute gravity and perceived gravity. It talked about how an object in free fall is weightless but still experiences gravity. It explained how G-force is not the same as gravity, because it can also be caused by acceleration, and it even showed some interesting experiments that demonstrate some of the concepts that were talked about.
