Work Energy Principle
In this video Paul Andersen explains how the kinetic energy gained by an object is equivalent to the work done on the object. The force on the object must act parallel or antiparallel to the motion of the object to do work. Several...

Brown Dwarfs Space’s Strangely Important Oddballs
You’d think it would be easy to tell if an object in space was a star or a planet - is it big, hot, and shining? It’s a star! Small, cool, and made of rock and gas? Planet! But cosmic oddities know as brown dwarfs remind us that the...

The Speed of Light is NOT About Light
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...

Multistep Reactions
In this video Paul Andersen explains how an overall chemical reaction is made up of several elementary steps. The stoichiometry of this equation can be predicted but the rate law must be measured. If the elementary steps of the reaction...

When Time Breaks Down
We learned how motion gives matter its mass, but how does motion affect time? Let's dive deeper into the true nature of matter and mass by exploring Einstein's photon clock thought experiment, and the phenomenon that is time dilation.

Conservation of Linear Momentum
In this video Paul Andersen explains how linear momentum is conserved in all collisions. In completely elastic collisions the kinetic energy of the objects is also maintained. Several examples and demonstrations are included.

Motion of the Center of Mass
In this video Paul Andersen explains how linear motion of an object can be measured using the center of mass. Internal forces within the object can be ignored since they exist in action reaction pairs. A simple way to determine the...
