What’s irrational and never ends? Pi! Hank explains how we need pi to explain some of the most basic but most important principles of the universe, in honor of Pi Day.

In this final segment on the four fundamental forces of physics, Hank tackles the magnetic force, the second of the two ways in which electromagnetism is apparent in the universe

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...

New ReviewIn this lesson we derive the change in gravitational potential energy for an object moving in a uniform gravitational field and then use that result as a direct analogy to determine the change in electric potential energy for a charge...

New ReviewIn this lesson, we explore the electric potential difference between two locations in the electric field of a point charge — one of the most essential concepts in AP Physics and introductory electrostatics. Using a positive point charge...

In this lesson we explore why the electric field between two ideal parallel plates is uniform and always directed from the positive plate to the negative plate. Using Coulomb’s law, symmetry arguments, and clear step by step reasoning,...

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...

Pupil outcome: I can describe how objects with a positive or negative charge attract or repel other charged objects. Key learning points: - Some objects can be charged by rubbing with certain materials. - Objects with a static electric...

A force is a push or a pull that acts on an object.



Forces are vector quantities because they have both magnitude and direction, and so can be represented by an arrow. Scalar quantities have only magnitude and no...

Continuous charge distributions are introduced and Coulomb’s Law is used to derive the integral equation which is used to find the electric field caused by a continuous charge distribution. Charge densities are...

In this video, we will determine the electric field at point P, which is located on the axis of a uniformly charged ring of charge Q and radius a, a distance x from the center of the ring. We will use Coulomb's law and an integral to...

This nugget explains the mathematical expression of work done in displacing a unit positive charge from 1 point to another.

Coulomb’s Law is introduced and compared to Newton’s Universal Law of Gravitation. “Point Charge” is defined. Micro, Nano, and Pico prefixes are explained. Two basic example problems are solved. And a the fact that the electric force is...
