This site, hosted by the University of Washington's Earth and Space Sciences Program, discusses an advanced plasma propulsion system that will enable spacecraft to attain unprecedented speeds, with minimal energy and...

The Physics Classroom presents this tutorial on momentum and its conservation. The three laws are three laws are explained and their application to the analysis of the motion of objects in one dimension is discussed....

This web page, authored and curated by David P. Stern, describes motion of an object traveling in a circle. The need for centripetal force to maintain the object's acceleration is derived using algebra and the Pythagoras...

This lesson plan, authored and curated by David P. Stern, provides an approach to teaching circular motion. It covers uniform circular motion, and the relation of its frequency with the peripheral velocity v, the radius...

This simulation displays the motion of a simple harmonic oscillator. The user can adjust the physical parameters in the problem including mass, spring stiffness, and damping. Graphs can be plotted relating any two...
