 Introduction Part 1 | File Type: video/mp4 | Duration: 28:08

Physics as a Description of the Universe Uncertainty in Measurement The Imperfect Notion of Trajectory Kinematic Quantities Defined Units and Dimensional Analysis Graphical Analysis Limitations of Kinematics

 Lecture 103: Derivatives Part II | File Type: audio/mpeg | Duration: 23:27

Lecture 103: Derivatives Part II

 Lecture 102: Derivatives | File Type: audio/mpeg | Duration: 43:50

Lecture 102: Derivatives

 Lecture 101: Kinematics | File Type: audio/mpeg | Duration: 44:19

Lecture 101: Kinematics

 Lecture 044: Capacitance | File Type: audio/mpeg | Duration: 29:57

Capacitance is defined in the context of an arrangement of parallel plates. The electric field energy per unit volume is also derived.

 Lecture 043: Equipotentials | File Type: audio/mpeg | Duration: 22:03

The notion of lines of equipotential is introduced and explored.

 Lecture 042: Parallel Conducting Plates | File Type: audio/mpeg | Duration: 19:09

The electric potential between two parallel conducting plates of known surface charge density is discussed in detail. This example is of particular interest because it is used to illuminate the relationship between force, field, voltage and energy.

 Lecture 041: Spherical Electrical Potentials | File Type: audio/mpeg | Duration: 24:46

The integral that defines electric potential is evaluated in the context of two uniform, spherically symmetric charge distributions, the first of which results in the electric potential due to a point charge.

 Lecture 040: Electric Potential | File Type: audio/mpeg | Duration: 12:26

The Electrostatic Potential energy is derived from the work-energy theorem which leads, in turn to our definition of electric potential, the energy per unit charge.

 Lecture 040: Electric Potential | File Type: audio/mpeg | Duration: 12:33

The Electrostatic Potential energy is derived from the work-energy theorem which leads, in turn to our definition of electric potential, the energy per unit charge.

 Lecture 031: Damped Oscillator | File Type: audio/mpeg | Duration: 27:10

The harmonic oscillator is solved with a damping force proportional to the speed of the oscillator.

 Lecture 030: Harmonic Oscillation Part II | File Type: audio/mpeg | Duration: 32:12

The principles of harmonic motion are reviewed and then applied to three examples: the simple pendulum, the physical pendulum and a can bobbing in water.

 Lecture 029: Harmonic Oscillation Part I | File Type: audio/mpeg | Duration: 38:12

The problem of a mass connected to a spring is analyzed using Newton's 2nd law to reveal the harmonic oscillator differential equation which is then solved for the position, velocity and acceleration of the oscillator as a function of time. Arguments are made that such solutions are approximately true for any system for which there exists a potential energy minimum, provided the oscillation is small. Also, it is demonstrated that identical solutions are obtained for a mass hanging from a vertical spring by applying a thoughtful change in coordinate.

 Lecture 028: The Motion of the Planets | File Type: audio/mpeg | Duration: 53:02

A modern demonstration of the discovery that a one over r squared force law results in planetary motions that are ellipses in agreement with Kepler’s observations.

 Lecture 027: Gravitational Potential Energy | File Type: audio/mpeg | Duration: 29:49

The gravitational potential energy between two mutually attracting bodies is derived. After, several essential applications of universal gravitation are presented.
