The following video narrated by Paul Andersen explains how electric circuits contain different elements which can be connected in series or in parallel. The following four elements are explained in detail; emf, resistor, capacitor, and...

The following video narrated by Paul Andersen explains how systems are two or more objects that interact with one another. If a system has no relevant internal structure it can be treated as an object. The conservation laws apply to...

The following video narrated by Paul Andersen explains how the energy, charge, and momentum in a system is conserved over time. [4:53]

The following video narrated by Paul Andersen explains how object interactions can add or remove mass or energy from a system. [2:14]

In this video Paul Andersen explains how the boundary between the system and environment is chosen to simplify analysis of a physics problem. [3:13]

In the following video Paul Andersen explains how conservative forces can be used to store potential energy in an object or a system. The work done is equal to the amount of potential energy in the object. The following conservative...

In the following 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. [4:46]

In the following 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. [6:45]

In the following video Paul Andersen explains how heat is the movement of energy from an object with a higher temperature to an object with lower temperature. Heat transfer can occur through conduction, convection, and radiation. [4:10]

In this video Paul Andersen explains how the First Law of Thermodynamics applies to an ideal gas in a piston. A pressure-volume graph can be used to determine the type of thermodynamic process. Included is a discussion of and P-V diagram...

In the following video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of...

In this, video Paul Andersen explains how Kirchhoff's Loop Rule can be used to calculate the voltage of different components of a circuit. The sum voltage throughout an entire loop will sum to zero following the law of conservation of...

In the following video Paul Andersen explains how Bernoulli's Equation describes the conservation of energy in a fluid. The equation describes the pressure energy, potential energy, and kinetic energy of a fluid at a single point. A...

Paul Andersen explains how the law of conservation of energy applies to both energy and mass. Einstein showed that mass and energy are equivalent and that the amount of energy contained within matter can be calculated using the famous...

In this video, Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object, the net total of charge will not change. [6:07]

In this video, Paul Andersen explains how Kirchhoff's Junction Rule can be applied to series and parallel circuits. Kirchhoff's Junction Rule is an application of the conservation of charge. The current into a junction will always equal...
