Episodes

Lecture 101: Kinematics

9/5/2018
More

Duration:00:46:10

Lecture 044: Capacitance

2/9/2018
More
Capacitance is defined in the context of an arrangement of parallel plates. The electric field energy per unit volume is also derived.

Duration:00:35:47

Lecture 043: Equipotentials

2/5/2018
More
The notion of lines of equipotential is introduced and explored.

Duration:00:22:02

Lecture 042: Parallel Conducting Plates

2/2/2018
More
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.

Duration:00:17:57

Lecture 041: Spherical Electrical Potentials

2/1/2018
More
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.

Duration:00:17:12

Lecture 040: Electric Potential

1/31/2018
More
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.

Duration:00:12:26

Lecture 031: Damped Oscillator

12/5/2017
More
The harmonic oscillator is solved with a damping force proportional to the speed of the oscillator.

Duration:00:27:10

Lecture 030: Harmonic Oscillation Part II

12/4/2017
More
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.

Duration:00:33:09

Lecture 029: Harmonic Oscillation Part I

12/1/2017
More
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...

Lecture 028: The Motion of the Planets

11/27/2017
More
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.

Duration:00:53:24

Lecture 027: Gravitational Potential Energy

11/22/2017
More
The gravitational potential energy between two mutually attracting bodies is derived. After, several essential applications of universal gravitation are presented.

Duration:00:29:49

Lecture 026: Universal Gravitation

11/20/2017
More
The formulation of Newton’s Universal Gravitational Law is explored in its historical context. After advice is given on applying the law, one of its consequences is revealed.

Duration:00:54:56

Lecture 025: Angular Momentum

11/13/2017
More
The angular momentum of a point particle is defined and discussed in the context of a classic demonstration.

Duration:00:39:24

Lecture 024: Rolling

11/9/2017
More
Rolling is described as a linear superposition of translational and rotational motion. A revelation is made regarding using the point of contact between the rolling object and the surface as the axis of rotation for the motion. The principles are applied to the problem of a sphere rolling down a ramp which is solved with two distinct approaches. After, the motion of a bowling ball skidding before rolling is presented as an essential problem.

Problem Solving: Torque

11/8/2017
More
The problem of a pulley with a single mass attached is solved two different ways; with Newton's 2nd Law and with Energy. The differences in these two approaches are discussed. Also, the problem of a rigid uniform rod rotating vertically about a hinge point is solved and the forces at the hinge are discussed.

Duration:00:39:16

Lecture 023: Torque

11/6/2017
More
Torque is demonstrated in the context of the classroom door and defined such that a rotational analog on Newton’s second law results. With this new version of the law, the problem of an Atwood’s machine with a massive pulley is solved.

Duration:00:39:38

Lecture 022: Moments of Inertia Part II

11/3/2017
More
The moment of inertia of a disk is derived and used to compare the dynamics of of a hoop and a disk of equal mass and radius as they roll down identical inclines. The fraction of energy transferred to rotational motion is discussed.

Duration:00:28:03

Lecture 021: Moments of Inertia Part I

11/2/2017
More
The moments of inertia are calculated for a few simple cases; a point particle, a hoop, a rod about its center of mass and a rod about its end. General observations are made about the properties of the moment of inertia including a derivation of the parallel axis theorem.
