Relativistic Addition of Velocity | Special Relativity Ch. 6
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...

Does Time Cause Gravity?
We know that gravity must cause clocks to run slow on the basis of logical consistency. And we know that gravity DOES cause clocks to run slow based on many brilliant experiments. But I never explained WHY or HOW gravity causes the flow...

The Trebuchet Challenge | Space Time
Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

Most Collisions Are Secretly in One Dimension
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...

Force-Time Graph
In this video Paul Andersen explains hot the force-time graph can be used to determine the impulse of an object. Since the impulse and the change in momentum are equivalent the graph can also be used to determine the change in momentum...

Complete Solution To The Twins Paradox
This video is about the famous 'Twins paradox' of special relativity, how time can appear to be faster for two different observers at the same time, and which twin really is older (or younger) - the one who stays on earth or the one who...

What If Dark Energy Doesn’t Exist?
Dark Energy is what we call the mysterious force that seems to be pushing the universe apart. By some calculations, it makes up 70% of everything in nature. Or...maybe it doesn’t exist at all! Plus, Juno’s observations give us new...
