This ThinkQuest site discusses distance and displacement, average velocity and instantaneous velocity, position-time graphs, velocity-time graphs, and relative motion. There are study questions and a quiz to test your understanding.
The next chapter of the ThinkQuest site described above continues with discussions of average acceleration and instantaneous acceleration, velocity-time graph displacement and constant acceleration, and acceleration due to gravity. (Click "Visit Site" if the "Oracle Thinkquest" page appears.)
This unit from The Physics Classroom site includes lessons on describing motion with words, describing motion with diagrams, describing motion with position-versus-time graphs, describing motion with velocity-versus-time graphs, free fall and acceleration of gravity, and describing motion with equations. The site includes animation.
This series of web pages and animations comprise a complete lesson on projectile motion covering independent vertical and horizontal velocities, the velocity vectors of a projectile, quadratic equations describing the motion, and launch angles other than zero. Includes assessment questions.
On this site students vary the angle and speed of projectiles to try to hit a target in six challenges of increasing difficulty and educational content. This nicely-done multimedia applet yields a real-time graph of the horizontal and vertical velocity components, as well as depicting the real-time vectors for those velocities.
This site includes two applets that 1) examine the effect of different projectile angles fired at the same speed and 2) examine the vector components of a projectile.
Introduction to angular momentum concept with real-life examples, glossary, and quiz.
Interactive demonstration on a graph of projectile motion.
Links to Angular Motion (rotations, angular velocity, angular acceleration)
Physics Multimedia Studio presentation on Centripetal Force.
This presentation will describe the physics (and math) of what occurs, for NON-physicist-types!
An interactive java applet.
This NASA Glen Research Center page discusses the fundamental concepts related to conservation of energy and mass flow. You can link to additional information on aerodynamics and propulsion.
This segment of the Interactive Heating, Piping, and Air Conditioning (HPAC) Engineering page, Air Systems Basics, discusses the laws of conservation applied to mass flow in air-handling systems. Reprinted with permission from Heating/Piping/Air Conditioning Engineering Magazine.
This page from a fluid mechanics course uses diagrams, mathematics, and example problems to aid in the understanding of mass flow rate and volume flow rate.
This page defines flow rate and then derives the continuity equation and Bernouilli's equation.
This chapter of Learn Physics Online introduces current. It also answers questions such as the following: Why can a bird sit on the power line? Why do many cows die during a thunderstorm even though lightning does not strike them directly? (Click "Visit Site" if the "Oracle Thinkquest" page appears.)
This site defines sinusoidal and talks about its properties as related to AC electricity.
This site will help you understand basic electrical circuit schematics.
This is an animated lesson on electricity. It requires a ShockwaveTM plugin.
This page describes series and parallel circuits and offers example problems.
An intermediate level discussion of temperature, thermometers, the kinetic theory of gas, and thermal radiation can be found here.
This page talks about heat flow and how to control it.
This is the Heat Transfer section of the HyperPhysics site. It contains discussions of heat transfer equations. Of particular interest are the examples of heat transfer that can be viewed by clicking on the Examples link.
This site on fiberglass insulation discusses conduction, convection, and radiation.
This site has links to several conversions, calculators, and sites covering a wide array of thermophysical properties.
