01 - Course Introduction and Newtonian Mechanics

01 - Course Introduction and Newtonian Mechanics

Professor Shankar introduces the course and answers student questions about the material and the requirements. He gives an overview of Newtonian mechanics and explains its two components: kinematics and dynamics. He then reviews basic concepts in calculus through two key equations: x = x0 + v0t + ½ at2 and v2 = v02+ 2 a (x-x0), tracing the fate of a particle in one dimension along the x-axis.

02 - Vectors in Multiple Dimensions

02 - Vectors in Multiple Dimensions

In this lecture, Professor Shankar discusses motion in more than one dimension. Vectors are introduced and discussed in multiple dimensions. Vector magnitude and direction are also explained. Null vectors, minus vectors, unit and velocity vectors are discussed along with their properties. Finally, several specific problems are solved to demonstrate how vectors can be added, and problems of projectile motion are expounded.

03 - Newton's Laws of Motion

03 - Newton's Laws of Motion

This lecture introduces Newton's Laws of Motion. The First Law on inertia states that every object will remain in a state of rest or uniform motion in a straight line unless acted upon by an external force. The Second Law (F = ma) relates the cause (the force F) to the acceleration. Several different forces are discussed in the context of this law. The lecture ends with the Third Law which states that action and reaction are equal and opposite.

04 - Newton's Laws (cont'd) and Inclined Planes

04 - Newton's Laws (cont'd) and Inclined Planes

The lecture begins with the application of Newton's three laws, with the warning that they are not valid for objects that move at speeds comparable to the speed of light or objects that are incredibly small and of the atomic scale. Friction and static friction are discussed. The dreaded inclined plane is dealt with head on. Finally, Professor Shankar explains the motion of objects using Newton's laws in specific problems related to objects in circular motion, such as roller coasters and a planet orbiting the Sun.

05 - Work-Energy Theorem and Law of Conservation of Energy

05 - Work-Energy Theorem and Law of Conservation of Energy

The lecture begins with a review of the loop-the-loop problem. Professor Shankar then reviews basic terminology in relation to work, kinetic energy and potential energy. He then goes on to define the Work-Energy Theorem. Finally, the Law of Conservation of Energy is discussed and demonstrated with specific examples.

06 - Law of Conservation of Energy in Higher Dimensions

06 - Law of Conservation of Energy in Higher Dimensions

The discussion on the Law of Conservation of Energy continues but is applied in higher dimensions. The notion of a function with two variables is reviewed. Conservative forces are explained and students are taught how to recognize and manufacture them.

Fantastic resource

Incredibly helpful for my AP Physics class. The professor doesn't just give you formulas and show you how to use them, he goes into a lot of depth showing how the formulas are derived and why they work. He is very clear but concise, may be too fast for some but that's why you can pause, rewind the video.

Amazing!!!

So so so helpful!! My uni has pod casts too but this guy is great. He doesnt just expect everyone to know what's going on. Also I love that he writes with chalk!

A Great Resource

I'm currently in an undergrad physics class, and these lectures are excellent for learning the background of the topics. Prof Shankar is a really good teacher; I don't know what I would have done in physics without his simplified, gradual explanation of these sometimes complex subjects.
He tends to focus more on the derivation of the formulas and the reasoning behind the laws, which might frustrate someone looking to take a more applied approach, but I suppose he figures that anyone can apply the formulas, the hard part is figuring out where they came from.

All in all, I would definitely recommend this to any student who wants to actually understand physics.
