It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...

In this video Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent the...

Hank builds a simple electric motor just powerful enough to make a small screw spin, but also strong enough to blow your mind.

In this video Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms (including chemical, mechanical, light, electrical, and thermal). In AP Chemistry students must be...

In this video Paul Andersen explains how energy can be transferred from one system to another. In a closed system the energy can be transferred as either work or heat. Thermal energy transfer is know as energy transfer through heat. ...

New ReviewIn this video, we build directly on electric potential energy and electric potential to develop a clear, conceptual understanding of electric potential difference. Using parallel plates and a uniform electric field, you will see where...

In this program heat energy is explored. The relationship between heat energy and temperature is highlighted. The relationship between phases changes and heat energy is also described. This video correlates to the Next Generation Science...

After 25 years of teaching physics, I realized I had been wrong about when you can use the equation Work due to nonconservative forces = Change in mechanical energy. In this video, I break down my mistake, show the correct way to think...

What happens when a satellite slows down in orbit? Learn how a small Δv transforms a circular path into an elliptical orbit, with step-by-step analysis of orbital energy, period, and arrival timing.

Welcome back to the Fluctus Channel for a feature about how monstrously powerful aircraft are kept in place while their engines are afterburning. Fluctus is a website and YouTube channel dedicated to sea geeks. Whenever you are curious...

Welcome back to the Fluctus Channel. In this episode, we delve into the complex propulsion systems of gigantic ships. Discover the ability of the ship to move in any direction through a propeller directed by the application...

Discover Torricelli’s Theorem, a fascinating result derived from Bernoulli’s Equation! Learn how to calculate the speed of fluid flowing out of a spigot in a large reservoir, why fluid density cancels out, and how this relates to the...

This video explains the concept of rotational kinetic energy stored in a flywheel, demonstrating its application in vehicles like trucks for efficient energy usage

This video demonstrates the principle of conservation of energy by solving a physics problem that determines the velocity of a ball at two different points during its projectile motion. It illustrates how mechanical energy remains...

This video explains the principle of conservation of energy by solving a problem involving a block moving on a frictionless U-shaped track. It demonstrates how potential and kinetic energy transform, allowing you to calculate the block's...

This video provides a detailed solution to a Grade 11 physics problem involving the work done by a spring force on a box on an inclined plane. It explains how to calculate the work done by the spring as the box moves and the concept of...

This video solves a physics problem calculating the change in potential and kinetic energy of a ball attached to a string as it swings down from a horizontal position, passing through a peg. It demonstrates energy conservation principles...

Understand how external and non-conservative forces affect mechanical energy. Learn to apply the work-energy theorem and energy statements for Physics students

Explore how potential energy diagrams reveal the interplay between force, position, and energy. Learn to interpret curves, apply F = -dU/dx, and calculate energy transformations using real physics problems.

Discover how mechanical energy—kinetic plus potential—remains conserved in systems under conservative forces. With real-world examples like roller coasters, this lesson simplifies a core law of classical mechanics.
