The third and final part of the block collision sequence.

A classic problem that Johann Bernoulli posed to famous mathematicians of his time, such as Newton, and how Bernoulli found an incredibly clever solution using properties of light.

A clever mechanical proof of Snell's law.

After a friend of mine got a tattoo with a representation of the cosecant function, it got me thinking about how there's another sense in which this function is a tattoo on math, so to speak.

Two proofs for the surface area of a sphere

Hans Christian Oersted had just discovered the connection between electricity and magnetism. Meanwhile, a French physicist named André-Marie Ampère was experimenting with some wires, trying to learn more about the connection between...

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...

In this video I take a trigonometric expression and multiply it by another trig expression.

When you need to remember how to graph the sine and cosine graphs quickly there is one thing you should remember. In this video that is what I want to explore with you.

In this video I am going to work through how to evaluate a basic trig function using the unit circle and one more difficult

Howcast - Learn how to perform self-hypnosis from clinical hypnotherapist Debbie Catz in this Howcast video.

Pupil outcome: I can use the verb 'ir' to say where I or we go and what I or we are going to do in the summer. Key learning points: - In Spanish, the SSCs [ce], [ci], and [z] are pronounced differently in different parts of the...

This lesson explores the relationship between work done by torque and a body's rotational kinetic energy. It covers the application of the work-kinetic energy theorem for rotating bodies, explains how to calculate work done by constant...

This video provides a step-by-step solution to a physics problem, demonstrating the application of Newton's Laws of Motion and kinematic equations to calculate force, distance, and work done for an object under constant deceleration

Learn how to solve inclined plane problems using Free Body Diagrams, force components, and Newton’s laws. Master tension, acceleration, and normal force calculations with step-by-step analysis

Learn how to calculate work done when force is applied at an angle to displacement. Explore vector components, dot product, and how angle affects positive, negative, or zero work in this essential Class 11 Physics lesson.

This video explains how to calculate angular displacement and other rotational kinematic variables for a rotating wheel, illustrating concepts like angular acceleration and revolutions.

This content delves into the physics of a falling cylindrical chimney, treating it as a thin rod rotating about its base. It uses energy conservation to determine the angular velocity and subsequently calculates the radial and tangential...

In this video, we are going to derive basic reciprocal and quotient identities, and then we will use those identities to simplify expressions.

In this video, we are going to derive the Pythagorean Identities (proofs) and then we will simplify expressions using these identities. We will work through 3 practice problems.
