The principles of kinesiology (the study of the mechanics of human motion) are applied to the energy, action, and reaction used in physical activities in this booklet designed for physical education teachers. In the first chapter, force is defined, and the production, application, and absorption of force are described and illustrated. Effects of…

Teaching procedures of Project Physics Unit 1 are presented in this manual to help teachers make effective use of learning materials. Curriculum objectives are discussed in connection with instructional materials, suggested year time schedules, multi-media schedules, schedule blocks, resource charts, and experiment summaries. Brief analyses are…

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 designed for college students who are non-physics majors, and is organized in sections of increasing sophistication. Section 1 presents ideas related to the kinetic theory of gases. Section 2…

Force diagrams involving angular velocity, linear velocity, centripetal force, work, and kinetic energy are given with related equations of motion expressed in polar coordinates. The computer is used to solve differential equations, thus reducing the mathematical requirements of the students. An experiment is conducted using an air table to check…

Gas flow patterns at a sampling nozzle are described in this presentation for the 12th Conference on Methods in Air Pollution and Industrial Hygiene Studies, University of Southern California, April, 1971. Three situations for sampling velocity are illustrated and analyzed, where the flow upstream of a sampling probe is: (1) equal to free stream…

Performance objectives are stated for each of the secondary school units included in this package of instructional guides prepared for the Dade County Florida Quinmester Program. All three units deal with mathematical applications or concepts in physics dealing with mathematical relationships: "Scientific…

Describes a kinetics experiment that utilizes timed reactions and colored endpoints and is suitable for large laboratory sections. (MLH)

Describes an experiment that utilizes spectrophotometric equipment to analyze the kinetics of a homogeneous reaction in batch. (MLH)

Distinguishes between the work done by the source and the work received by the system. Shows that a comparison of the magnitudes of quasistatic and nonstatic work can be carried out only through the use of the laws of thermodynamics. (GA)

Derives an equation relating the internal pressure of a rubber balloon to its radius. Shows that the theoretical pressure curve is experimentally verifiable, and discusses the problem of equilibrium configuration of two interconnected ballons. (Author/GA)

Reports a consecutive first-order reaction for which the concentrations of reactant, intermediate, and products can be determined simulataneously. This reaction is the epoxidation of 2,5-di-tert-butyl-1,4-benzoquinone (I) by alkaline hydroperoxidation using tert-butyl hydroperoxide and benzyltrimethylammonium hydroxide (Triton B) catalyst.…

Describes an experiment in which the kinetics of dimerization of nitrosamine induced by a flash of light is measured. The experiment can be performed with a commercial ultraviolet-VIS spetrophotometer with easy to make modifications. The experiment demonstrates a flash photolysis system not always available in university chemistry laboratories.…

Describes how to modify the commercially available and inexpensive Griffin-Worden (Kontes) glass pressure reactors to permit sampling of homogeneous reactions, without changing the relative concentration of species present. All required parts necessary for the modification are commercially available. (JN)

Background information, procedures used, and typical results obtained are provided for an experiment in which the stability constants of unstable complexes are determined. (JN)

Describes the theory and performance of a diffusion experiment based on the free boundary method. Suitable for biochemistry and microbiology students taking physical chemistry. (MLH)
