Position, Velocity and Acceleration
In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Electrochemistry
In this video Paul Andersen explains how electrochemical reactions can separate the reduction and oxidation portions of a redox reactions to generate (or consume) electricity. The half reactions can be analyzed to determine the potential...

Density
In this video Paul Andersen explains how density measures the compactness of a material. You can calculate the density of a material by measuring the mass and dividing this by the volume. Water displacement is an effective way to measure...

Kinetic and Potential Energy
In this video Paul Andersen explains how the energy in a closed system can be converted from kinetic to potential to kinetic energy. Sample problems and a simulation is contained.

Stoichiometry
In this video Paul Andersen explains how stoichiometry can be used to quantify differences in chemical reactions. The coefficients in a balanced chemical equation express the mole proportions in that reaction. These values can be used to...

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...
