Traces the men, experiments, and hypotheses involved in elucidating the nature of molecular motion from the work of Robert Brown in 1827 to Einstein in 1905. (GS)

Presents a simple means for extending the Bohr model to include relativistic corrections using a derivation similar to that for the non-relativistic case, except that the relativistic expressions for mass and kinetic energy are employed. (Author/GS)

This tennis stroke analysis, based on the application of biomechanic principles, is designed to help those who play tennis only once or twice a week. It is noted that, because the tennis player has a limited power potential, the only way to increase his racket head speed is to rotate his body. The mechanics of tennis are discussed by dividing it…

As a supplement to Project Physics Unit 1, 21 articles are presented in this reader. Concepts of motion are discussed under headings: motion, motion in words, representation of movement, introducing vectors, Galileo's discussion of projectile motion, Newton's laws of dynamics, the dynamics of a golf club, report on Tait's lecture on force, and bad…

This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. It describes a series of experiments designed to demonstrate the behavior of a system of macroscopic particles whose interactions are of very short range. The apparatus for the experiments include a…

A model demonstrating the relationship between the structure of blood vessels and the flow of blood is described and illustrated in the biology section of the newsletter. The apparatus also contains a functional (but not structural) model of the heart. Suggestions for the preparation of a relatively permanent dialysis bag from visking tubing are…

An analysis of the minimum stopping distance problem is presented taking into account the effect of weight transfer on nonskidding vehicles and front- or rear-wheels-skidding vehicles. Expressions for the minimum stopping distances are given in terms of vehicle geometry and the coefficients of friction. (Author/BB)

A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

Part l (SE 538 305) covered application of classical thermodynamics, polymer crystallinity, and phase diagrams to teaching physical chemistry. This part covers statistical thermodynamics, conformation, molecular weights, rubber elasticity and viscoelasticity, and kinetics of polymerization. Eight polymer-oriented, multiple-choice test questions…

Eight men participated in three randomized maximal oxygen uptake tests to investigate the hypothesis that the use of toe clips on bicycle ergometers produced a higher VO2 max. No significant difference in mean VO2 max or performance time was observed. (Author/MT)

Describes a program which simulates the kinetic behavior of a "typical" enzyme. Program objectives, background to the kinetic model used in the simulation, major program features, typical results obtained, and a note on the availability of the program (written in BASIC for Commodore microcomputer) are included. (JN)

Background information, apparatus needed, procedures used, and results obtained are provided for a simple kinetic method for the monitoring of adsorption processes. The method, which involved adsorption of crystal violet onto activated carbon, is suitable for classroom and/or research purposes. (JN)

Gives a numerical example of the steady-state assumption, using three calculations for the free radical decomposition of methane. (MLH)

Describes a procedure for studying the kinetics of the second-order hydrolysis of ethylene bromohydrine in alkaline medium by incorporating a substance that changes color as one of the reacting components is depleted. (MLH)

Describes a laboratory experiment that utilizes NMR Spectroscopy to determine the rate constant for the C-N bond rotation in dimethylacetamide. (MLH)
