摘要:

Ideally, every physics lesson, every lecture, every lab should be built around a question. The teacher should use the question as framework and should make the question explicit for the student.

摘要:

An advertisement showing a set of photographs of a car accelerating from rest along a straight road is analyzed. It is found that the times marked on the photographs must be incorrect, and a revised analysis is presented.

摘要:

Star Warstakes place in another galaxy in another age and the adventure plays out on “inhabitable” planets unknown to us. Yet, it is curious how all the planets and other astronomical bodies of different sizes and compositions thatStar Warscharacters visit seem to have the same gravitational field at the surface.

摘要:

It’s about time vectors were taught more widely in their complete form,together with diagrams, to let students see how delightfully simple the world of motion is.

摘要:

As the basis for understanding music, quantum mechanics, and optical phenomena, standing waves are tremendously important, but instructors with a shoestring budget may not be able to do laboratories for them. However with simple modification of an inexpensive aquarium aerator costing a few dollars, instructors can take that shoestring and make standing waves.

摘要:

A few weeks ago our volleyball coach telephoned me with a problem: How high should a player jump to “spike” a “set” ball so it would clear the net and land at a known distance on the other side of the net?

摘要:

During the first semester of our calculus-based introductory physics course sequence, students work in small groups on mechanics projects. Many teams choose digital video analysis for projects involving mechanics. We discuss the management of collaborative projects and schemes for critiquing collaborative papers and assigning individual grades. We also describe some of the more interesting projects. Finally, we offer some advice on how to find the information needed to create good digital video movies.
