This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It is intended for college students who are not preparing to become professional physicists. The monograph contains three chapters. Chapter 1 deals with the law of inertia for objects at rest and in…

This booklet contains five research works on kinesiology, the study of the principles of mechanics and anatomy in relation to human movement. The first article explains the use of Web graphics in isolating five movements: effort, force, balance, flexibility, and swing. The process for pinpointing values on the Web grid is presented in two sheets…

This report contains articles on research in kinesiology, the study of the principles of mechanics and anatomy in relation to human movement. Research on sequential timing, somatotype methodology, and linear measurement with cinematographical analysis are presented in the first section. Studies of the hip extensor muscles, kinetic energy, and…

Provides directions for a three person rotating reference system. A series of experiments used with the apparatus is also described. (CP)

Describes experiments which could be performed on an 1860 rotating table apparatus. (CP)

Tries to clarify and explain some inaccuracies that appeared in a recent article dealing with a current induced in an external circuit due to charges moving within a device, an ionization chamber of planar geometry, in the circuit. (GA)

An approximate method is developed for elastic scattering at large angle in the framework of classical mechanics. A simple formula for differential cross-section is obtained. (Author/BB)

Explains the concept of jerk and resolves it, for planar motion, into two components: tangential-normal and radial-transverse. Expresses the normal component in terms of an affine differential invariant, the aberrancy. Uses aberrancy properties to establish geometrical properties of the jerk vector for plane motion. (GA)

Discusses the criteria and procedure for optimizing the performance of Archibald rubber-band heat engines by using the appropriate choice of dimensions, minimizing frictional torque, maximizing torque and balancing the rubber band system. (GA)

Shows using the special theory of relativity, how a body acted upon by a force with positive components could have one or two negative acceleration components. (GA)

Includes eleven short notes, comments and responses to comments on a variety of topics such as uncertainty in a least-squares fit, display of diffraction patterns, the dark night sky paradox, error in the dynamics of deformable bodies and relative velocities and the runner. (GA)

Obtains the orbits with reference to the center of mass of two bodies under mutual universe square law interaction by use of the eccentricity vector which is equivalent to the Lenz vector within a numerical factor. (Author/SL)

Provides a detailed discussion of a Lagrange formalism in classical momentum space. (SL)

Described is a novel approach to the teaching of projectile motion of sixth form level. Students are asked to use an analogue circuit to observe projectile motion and to graph the experimental results. Using knowledge of basic dynamics, students are asked to explain the shape of the curves theoretically. (Author/MA)

Demonstrates that investigating coriolis effects in a fixed frame leads to a clearer understanding of the physical nature of the phenomenon. (SL)
