Part 1 of the series looked at teaching speed and velocity. Part 2 considers the teaching of acceleration in physics. Teachers may find it okay to hurry through the concepts of speed and velocity because they are intuitive. But teachers cannot hurry through acceleration quite so quickly because it is not intuitive. Whereas velocity is a rate of…

Some introductory physics courses begin where student interest is thought to be highest--in waves, sound, and light--before speed, velocity, and acceleration. For students with math difficulties, this order makes sense. But most physics courses, including the author's own, begin with a study of motion. Why? Mostly due to tradition, he admits. When…

This article presents suggestions for integrating the phenomenon of hurricanes into the teaching of high school fluid mechanics. Students come to understand core science concepts in the context of their impact upon both the environment and human populations. Suggestions for using information about hurricanes, particularly Hurricane Katrina, in a…

Explores the basic physics behind pulling a tablecloth out from under a set of dishes, glassware, and utensils without disturbing them. Discusses terminology of Newton's laws of motion and illustrates them using three simple examples. (NB)

At the end of a secondary school science study of mechanics, a summary lab uses a motorcycle to provide students with the chance to apply some of the concepts they have studied. Exercises from this motorcycle physics lab are discussed. (Author/JN)

Describes a number of demonstrations for physics that employ techniques of the martial arts to illustrate Newton's second law of motion. Demonstrations focus on the breaking of wooden boards using weights. (DDR)

Suggests techniques to help eliminate students' misconceptions involving Newton's Third Law. Approaches suggested include teaching physics from a historical perspective, using computer programs with simulations, rewording the law, drawing free-body diagrams, and using demonstrations and examples. (PR)

Two physics experiments are described, One, involving a laboratory cart accelerated along a level surface, examines the concept of inertial mass in translation and the other, using a solid cylinder, measures the moment of inertia of a wheel. Equations and illustrations are included. (MA)

Nanoscience refers to the fundamental study of scientific phenomena, which occur at the nanoscale--nanotechnology to the exploitation of novel properties and functions of materials in the sub-100 nm size range. One of the underlying principles of science is development of models of observed phenomena. In biology, the Hardy-Weinberg principle is a…

Presents a method for teaching aspects of mechanics using juggling. This approach requires an understanding of the three ball juggling pattern. Recommends teacher-guided deconstruction of the ball motion and discusses acceleration, force, gravity, impulse, and momentum. (DDR)

Describes the involvement of students in the construction of an inexpensive wooden balance to aid in their understanding of mass. (ZWH)

Describes a hands-on activity in which the student's task is to design testing procedures and use appropriate formulas to meet the objectives of a two-dimensional projectile motion lab. (ZWH)

Analyzing real motion with frame-by-frame precision can be conducted using modestly priced digital-video camcorders. Although well below the 1,000 frames-per-second threshold of high-speed cameras, commercially available camcorders grab 30 frames per second. A replay dissected at this lower frequency is fun to watch, challenges students'…

Suggests taking physics to a playground to manipulate the apparatus and to examine the equipment; applying physical principles such as the pendulum model to swings and angular momentum to the merry-go-round. (BR)

Reports concepts which 12th-grade physics students hold about motion before and after a lecture is given. Compares quantitative and qualitative research methodology and describes some responses to test items. Shows six questions, student responses, and typical incorrect explanations used by students. (YP)
