Fluid Dynamics
Explore fluids in motion. Energy conservation requires low pressure where fluid velocity is high, and vice versa. This relation between pressure and velocity results in many practical and sometimes counterintuitive phenomena, collectively called the Bernoulli effect: explaining why baseballs curve and how airplane speedometers work.

Causes of Motion
For most people, the hardest part of learning physics is to stop thinking like Aristotle, who believed that force causes motion. It doesn't. Force causes change in motion. Learn how Galileo's realization of this principle, and Newton's later formulation of his three laws of motion, launched classical physics.
Falling Freely
Use concepts from the previous episode to analyze motion when an object is under constant acceleration due to gravity. In principle, the initial conditions in such cases allow the position of the object to be determined for any time in the future, which is the idea behind Isaac Newton's clockwork…
Rotational Motion
Turn your attention to rotational motion. Rotational analogs of acceleration, force, and mass obey a law related to Newton's second law. This leads to the concept of angular momentum and the all-important -conservation of angular momentum, which explains some surprising and seemingly counterintuitive phenomena involving rotating objects.
Newton’s Laws Of Motion
Physics is frequently one of the hardest subjects for students to tackle because it is a combination of two of the toughest subjects for most students: Math and Word Problems. What sets this series apart from other physics teaching tools is that the concepts are taught entirely through step-by step…
Newton’s Laws Of Motion With Friction
Physics is frequently one of the hardest subjects for students to tackle because it is a combination of two of the toughest subjects for most students: Math and Word Problems.

History's Mysteries
Begin this journey by taking a closer look at concepts that were once unexplainable but are now better understood. You'll focus on two such former mysteries: the existence of an invisible "aether" through which light and sound were believed to travel and the orbit of Mercury, which seemed to violate…
Describing Motion
Motion is everywhere, at all scales. Learn the difference between distance and displacement, and between speed and velocity. Add to these the concept of acceleration, which is the rate of change of velocity, and you are ready to delve deeper into the fundamentals of motion.
The Science of Information - From Language to Black Holes
The science of information is the most influential, yet perhaps least appreciated field in science today. Never before in history have we been able to acquire, record, communicate, and use information in so many different forms. Never before have we had access to such vast quantities of data of every…
Earth, Ether, Light
Review the famous Michelson-Morley experiment, which was designed to detect the motion of Earth relative to a conjectured ether wind that supposedly pervaded all of space. The failure to detect any such motion revealed a deep-seated contradiction at the heart of physics.
