Have you ever heard the phrase, 'You look like a Million Bucks?' Well, you do... but you also look like a million particles. In this episode, Sabrina talks to us about matter and particles and that all matter is made up of particles....

Particle physics isn't simple, but it was much more confusing before physicists knew about quarks.

In this video Paul Andersen explains how light can be treated as both a particle and a wave. Physicists use scale to determine which model to use when studying light. When the wavelength of light is equivalent to the size of the object...

The weak force has been causing trouble for a century, ruining everything physicists thought was true. But it might actually be responsible for your very existence.

In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

In this video Paul Andersen explains how a charge particle will experience a magnetic force when it is moving through a magnetic field. The right-hand rule is described as a method for determining the direction of the force. The...

Lots of people believe the Universe is infinite, but there's a good possibility that might not be the case. Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant?

Stars blowing up is a surprisingly common occurrence, but who would have thought to search the bottom of the ocean if you were trying to study them?!

Physics investigates why the universe behaves the way that it does, and today, Hank tells us about the three physics experiments that he thinks were the most awesome at helping us understand how the universe works.

Hank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an...

In this episode, Hank welcomes you to the new age, to the new age, welcome to the new age. Here he'll talk about transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission....

Neutrons don't change into protons. Except, sometimes, they do. Radioactivity is the process under which the nucleus can change spontaneously from one element to another. Steve Weatherell suggests that we acknowledge both the usefulness...

Beyond what we can touch, taste, smell, and hear, we experience the universe through light. But how did we come to discover light, and how did we learn light's true nature, as the fastest thing in the universe, an electromagnetic...

Hank reports on some new discoveries: one which points towards the existence of dark matter with the "majorana particle" and another, which points towards the existence of life on Mars. Exciting stuff!

In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

New ReviewIn this lesson, we compare electric potential energy and gravitational potential energy for a proton moving between parallel plates in a uniform electric field, and we plug in realistic values to show just how small the gravitational...

New ReviewThis video uses colorful imagery and animations to illustrate how matter is made of tiny particles. The nature of atoms and molecules is explored through instructive imagery. The video correlates to the Next Generation Science Standard...

Explore laminar flow and streamlines with this animation of ideal fluid particles moving through a narrowing pipe. See how particle paths and streamlines illustrate fluid motion, perfect for understanding fluid dynamics.

Explore how the gravitational force and potential energy behave along the central axis of a planet’s ring system. Learn how symmetry simplifies the math and how energy conservation reveals the particle’s speed through the ring’s center.

Master key physics concepts like escape velocity, projectile height, and impact speed using energy conservation on a low-gravity asteroid—ideal for AP and IB exam prep

Learn how to calculate gravitational attraction between a point mass and a uniform rod using integration and Newton’s law of universal gravitation—essential for advanced physics students.

SUMMARY:

Quantum field theory or QFT is the basis of the best theory we have in physics today to explain nearly everything, called the Standard Model of particle physics. What is Quantum Field theory? Why is it...

Explore what happens if you fall straight through Earth—using Newton’s Shell Theorem, simple harmonic motion, and real gravitational data. Understand why every straight tunnel gives the same 42-minute trip, and how gravity behaves inside...

Learn how to calculate gravitational force on a particle due to multiple masses using the principle of superposition. This lesson breaks down vector addition, force from extended bodies using integrals, and how to apply Newton’s law of...
