Describes the use of catapults as a way to increase math, science, and technology correlations within the classroom. Includes detailed instructions, a list of materials for building a catapult, and print and Internet resources. (JOW)

This minicourse was prepared for use with secondary physics students in the Dallas Independent School District and is one option in a physics program which provides for the selection of topics on the basis of student career needs and interests. This minicourse was aimed at providing the student with an understanding of the physics of falling…

Three converging findings suggested that long movements are under feedback control whereas short movements are predominantly programmed and ballistic in nature. (Author/RK)

Three experiments examined the role of various sources of feedback in the development and maintenance of a complex ballistic skill, dart throwing, using extended practice. (Editor)

Describes a circuit designed to measure time-of-flight velocity and shows how to use it to determine bullet velocity in connection with the ballistic pendulum demonstration of momentum conservation. (Author/GA)

Desktop manufacturing is the use of data from a computer-assisted design system to construct actual models of an object. Emerging processes are stereolithography, laser sintering, ballistic particle manufacturing, laminated object manufacturing, and photochemical machining. (SK)

Two experiments are described which investigated whether results obtained in studies of static flexibility tranfer to dynamic flexibility. In both experiments, subjects were assigned to a group receiving proprioceptive neuromuscular facilitation training, ballistic stretching technique training or a control group. Results are presented and…

A problem is detailed which has a solution that embodies geometry, trigonometry, ballistics, projectile mechanics, vector analysis, and elementary computer graphics. It is felt that the information and sample computer programs can be a useful starting point for a user written code that involves missiles and other projectiles. (MP)

Traces the theoretical significance of using names as titles for situations, and applies this analysis to the United States' intercontinental ballistic missile (ICBM) programs. Argues that the names given to ICBMs preserve their utility as weapons by linking them to the myths of the nineteenth-century western frontier. (MM)

The present study suggests that post-KR delay interval time or activity in the interval has little to do with learning on a self-paced positioning task, not ruling out that on ballistic tasks or more complex nonballistic tasks that a learner could make use of additional time or strategy. (MB)

Addresses the strategy and policy implications of effective ballistic missile defense and the scope/priorities of a research program underway to determine its technical feasibility. Several types of "smart bullets" are described, along with sensing devices for space, air, and ground. Procedures established to centrally plan/control the program are…

Presents general systems models (ballistic system, guided system, and adaptive system) and an evaluation matrix to help in examining training evaluation alternatives and in deciding what evaluation is appropriate. Includes some guidelines for conducting evaluation studies using four designs (control group, reversal, multiple baseline, and…

A study attempted to determine whether force and duration parameters are programmed in an interactive or independent fashion prior to executing ballistic type isometric contractions of graded intensities. Four adult females each performed 360 trials of producing ballistic type forces representing 25, 40, 55, and 75 percent of their maximal…

Morrison's critique of the Reagan Administration's Strategic Defense Initiative is representative of the views of those who oppose ballistic missile defense (Georgia Social Science Journal; v16 n2 p12-14 Spr 1985). Morrison's analysis is thoughtful, well structured, and well presented. However, it is quite wrong. Fallacies in his analysis are…
