This applet displays the motion of two blocks. One of them is moving on a level surface and the other one along a curved surface, the curve of which can be changed. The initial velocity of the blocks, equal for the two...
This activity from the Exploratorium contains an introduction to diamagnetic materials like water that are repelled by both poles of a magnet. A rare-earth magnet is used to repel grapes, whose main component is water,...
This web page explains the physics of sonic shock waves. Text and animations describe and illustrate the wavefronts of sound from a moving point source for the cases of motion equal to, less than, and greater than the...
This research studies students' functional understanding of magnetic induction, the process by which changing magnetic flux induces electrical current in a circuit. Functional understanding includes the ability to...
One commonly stated instructor goal for an introductory calculus-based physics course is to improve students? problem solving skills. There is, however, a growing body of research evidence to suggest that this goal is n...
