This applet illustrates the motion of an object in different reference frames. A block moves with a constant velocity on a second object that is also moving. The displacement vectors are shown as a vector sum. The...
This applet displays the motion of an object moving with constant acceleration. As a model of a car slowing to a stop, the object initially moves with uniform velocity when brakes are applied. The initial velocity,...
This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic...
This web site offers a multimedia presentation on the properties of the hydrogen atom and the ways in which these properties are commonly visualized. Pictures and animations of states of the atom are presented with...
