👉 Learn how to find the derivative of an implicit function. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the variable x. The process of finding the derivative of a...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on the conservation of energy. Two examples are included in the video and two additional examples are included in the linked thinking slides. ...

Want to learn more about the topic in this week's video? Here are some key words/phrases to get your googling started: - Lifting Condensation Level (LCL): The altitude at which the water vapor in rising air begins to condense - Adiabatic...

In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant...

Mr. Andersen explains the difference between potential and kinetic gravitational energy. He also uses physics to calculate the energy in various objects.

Summary:

Everything you can see is made of up of the same fundamental particles. The best theory of fundamental particles and forces is the Standard model of particle physi
