This video is chapter 6 in my series on special relativity, and it covers the topic of relativistic addition of velocity: aka, how things that are moving relative to one inertial reference frame, which is moving relative to another...

What if you thought the earth was flat? And then you found out it isn't?

This video is about elastic and inelastic collisions in 1D, 2D and 3D - and how the collision of conservation of energy with conservation of momentum, plus a secret direction, results in a completely predetermined behavior for most...

This video is about the Portal Paradox - a paradox in the video game Portal (and Portal 2) regarding whether or not a companion cube passing through a moving portal plops out of the other end with no speed (velocity,...

The speed of light is often cited as the fastest anything can travel in our universe. While this might be true, the speed of light is the EFFECT and not the CAUSE of this phenomenon. So what's the cause? On this week's episode of Space...

The Andromeda galaxy is heading straight toward our own Milky Way. The two galaxies will inevitably collide. Will that be the very last night sky our solar system witnesses?

In this video Paul Andersen explains how the macroscopic measure of temperature can be related to the average kinetic energy of molecules in motion. The Boltzmann constant and distribution can be used to calculate the root mean square...

Showing relative motion of two cars from the sky!

Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time...

A video entitled “Velocity” which defines the term velocity and shows how velocity is measured by examining the equation used to solve for its value.

Identifying the spring force, acceleration, and velocity at the end positions and equilibrium position of simple harmonic motion. Amplitude is also defined and shown.

This video covers the applications of eigenvectors and eigenvalues (in and outside of mathematics) that I definitely didn't learn in school. <b<b<b<br/>r/>r/>r/>

It's been called "the Queen of Sciences"--mathematics. It might not be as obvious in Olympic sports as physics or materials-engineering, but math--from simple arithmetic to calculus--is part of every jump, every spin, every move the...

To solve these types of problems, I think it's helpful to follow these steps:<b<br/>r/>
1) De<br/>fine positions
2) Find length
3) Differentiate

The best way to understand how tangential velocity and tangential acceleration are related is to visualize from above. Will you look at that! This video does exactly that.

Lesson 13 (Collisions) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this video: 1. Are...

In this video I prove that the work done by the force due to gravity (assumed to be constant and downwards) is equal to the change in gravitational potential energy.

An elastic collision is demonstrated and analyzed.

This nugget explains about the relative velocity with some special cases.

Students sometimes have a difficult time understanding what acceleration in meters per second squared really means. Therefore, I present acceleration as meters per second every second instead. This helps students gain a better...
