Impulse
In this video Paul Andersen defines impulse as the product of the force applied and the time over which the force is applied. The impulse of an object is equivalent to the change in momentum of the object. Several problems related to...

Momentum
In this video Paul Andersen will first define momentum as the product of an objects mass and velocity. He will then demonstrate how a net force acting on an object will change the momentum in the direction of the force. Several problems...

Solving the Puzzle of Plate Tectonics
Why do Africa and South America fit together? Anyone who's ever looked at a map can see that Earth's continents are kind of like a jigsaw puzzle. The idea that continents are constantly moving and weren't always in their current spots is...

The Bohr Atom
In this video Paul Andersen describes the major parts of an atom and explains how the Bohr Model more accurately represents the location of electrons around the nucleus. Niels Bohr refined the Rutherford model to account for spectra.

Wave Interference
In this video Paul Andersen explains how waves interact with objects and with other waves. When a wave hits a fixed object it will be reflected and inverted. When a wave hits a free object it will be reflected without being inverted....

Organ Systems
Paul Andersen explains how organs work together to form organ systems and how organ systems work together to form organisms. The kidney and bladder work together to filter blood in the excretory system. The circulatory and respiratory...

PS2C - Stability and Instability in Physical Systems
Paul Andersen explains how physical systems remain stable and unstable over time. The sum total of interactions acting on the system determine its stability. Feedback loops are used to maintain stability but require energy. If the energy...

Work and Power
In this video Paul Andersen explains how the work is a product of the external force applied to an object or system and the distance it moves. Power is a measure of the amount of work done per unit time. The work can be calculated as the...
