The Second Law of Thermodynamics
Trace the history of the second law of thermodynamics, considered by many physicists to be the one law of physics most likely to survive unaltered for the next thousand years. The second law says that entropy--the degree of disorder in a closed system--only increases or stays the same.
Entropy: The Second Law of Thermodynamics
Turn to an idea that has been compared to a work of Shakespeare: the second law of thermodynamics. According to the second law, entropy, a measure of disorder, always increases in a closed system. Order can only increase at the cost of even greater entropy elsewhere in the system.
Heat Engines and the Second Law of Thermodynamics
This program covers the important topic of heat engines and the second law of thermodynamics in Physics. We begin by discussing the theory, which involves how useful work can be done by engines which use expansion or hot gases to move a piston. The entire lesson is taught by working…
Reversibility and the Laws of Physics
Isaac Newton's laws of physics are fully reversible; particles can move forward or backward in time without any inconsistency. But this is not our experience in the world, where the arrow of time is fundamentally connected to irreversible processes and the increase in entropy.
Using Newton's Laws: 1-D motion
Investigate Newton's second law, which relates force, mass, and acceleration. Focus on gravity, which results in a force, called weight, that's proportional to an object's mass. Then take a ride in an elevator to see how your measured weight changes due to acceleration during ascent and descent.
Newton's Laws in 2 and 3 Dimensions
Consider Newton's laws in cases of two and three dimensions. For example, how fast does a rollercoaster have to travel at the top of a loop to keep passengers from falling out? Is there a force pushing passengers up as the coaster reaches the top of its arc? The answer…
Consequences of the Second Law
The second law puts limits on the efficiency of heat engines and shows that humankind's energy use could be better planned. Learn why it makes sense to exploit low-entropy, high-quality energy for uses such as transportation, motors, and electronics, while using high-entropy random thermal energy for heating.
Electric Charge & Coulomb's Law Part 1
This program covers the important topic of Electric Charge and Coulomb's Law in Physics. We begin by discussing what electric charge is and what coulomb's law is. We take time to introduce the units to the student so that there is no confusion as to what the problem is asking.…

Gauss' Law Part 1
This program covers the important topic of Gauss' Law in Physics. We begin by discussing what Gauss' Law is. Next, we introduce the theory behind Gauss' Law and use diagrams to describe why it is important. The entire lesson is taught by working example problems beginning with the easier ones…
