Lecture Series on Classical Physics by Prof.V.Balakrishnan, Department of Physics, IIT Madras.

There are many different ways that you can go about solving engineering problems.  One of the most important methods is energy analysis.  Energy is a physical property that allows work of any kind to be done; without it, there would be no motion, no heat, and no life.  You wouldn’t be able to get out of bed in the morning, but it wouldn’t matter, because there would be no sun.  Without energy, our world would not exist as it does. Thermodynamics is the study of energy and its transfers though work.  It is the link between heat and mechanical exertion.  Once you have a solid grasp on thermodynamic concepts, you should be able to understand why certain mechanisms (such as engines and boilers) work the way they do, determine how much work they can put out, and know how to optimize these power systems.   A thorough understanding of thermodynamics is crucial to any career that focuses on HVAC systems, car engines, or renewable energy technology. This course will focus on the fundamentals of thermod…

Physics 101 is the first course in the Introduction to Physics sequence. In general, the quest of physics is to develop descriptions of the natural world that correspond closely to actual observations. Given this definition, the story behind everything in the universe, from rocks falling to stars shining, is one of physics. In principle, the events of the natural world represent no more than the interactions of the elementary particles that comprise the material universe. In practice, however, it turns out to be more complicated than that. As the system under study becomes more and more complex, it becomes less and less clear how the basic laws of physics account for the observations. Other branches of science, such as chemistry or biology, are needed.  In principle, biology is based on the laws of chemistry, and chemistry is based on the laws of physics, but our ability to understand something as complex as life in terms of the laws of physics is well beyond our present knowledge. Physics is, however, the…
