Electromagnetism, along with mechanics, is one of the most fundamental disciplines in physics, and the magnetic force is one of the most easily accessible forces existing in nature. Magnets are often used as science teaching aids and are readily available from a young age; the forces of these magnets are first dealt with in NGSS (Next Generation…

Discusses the work and energy involved in walking on horizontal surfaces. (MLH)

Photographs show three simple demonstrations of deceptive centers of gravity. (CP)

The circular motion observed when water drains into a smooth opening is analyzed. This action, as well as cycloidal atmospheric motion, is explained as the result of rotation of the coordinate system. (CP)

In the first part of this article, brief reviews were given of the atomic-scale mechanisms by which crystalline solids deform and the nature of the interface between such solids and their environment. In this part, the mechanisms of a representative range of surface and environment sensitive mechanical phenomena are explained. (Author/CP)

Diagrams and photographs are incorporated in an explanation of the physics involved in the skills of diving and swimming. (CP)

Presents an application of the formulas of kinematics to the real driving situation, involving motion at constant speed and deceleration. Suggests the problem be used as an example in class, a homework assignment, or a test item. (CC)

Photographs illustrate several principles of physics which can be observed in everyday situations. (CP)

Constructs a magnetic field model that illustrates by analogy the dynamic lift on an airplane wing. (MLH)
