The effects of force level and force direction on force discrimination and isometric tracking performance
… was used to examine the effects of variation in force magnitude, force direction, and direction of target movement upon tracking performance. A contralateral force-matching procedure was also employed to assess the effects of variation in force level and force direction upon force discrimination …

The All-Volunteer Force and Presidential Use of Military Force
The creation of the All-Volunteer Force (AVF) in 1973 allowed U.S. presidents to deploy American military power in times and places of their own choosing with fewer concerns that the electorate would turn against their leadership. A reaction to the trauma of the Vietnam War, the AVF did away with …

The Future Force and Insurgents: A Need For Balance in Force Transformation
Force Transformation is a continuing process to reform the U.S. Army into a smaller, more lethal force utilizing the latest technologies, resulting in the Future Force. The process would create vulnerabilities that would increase the number of unnecessary casualties, degrading their combat …

Police Use of Force Databases: Sources of Bias in Lethal Force Data Collection
Understanding police use of lethal force requires the collection of reliable data. Due to bias present in police-use-of-lethal-force databases, researchers typically triangulate using multiple data sources to compensate for this bias; however, triangulation is restricted when the bias present in …

The Effect of Force Feedback on Student Reasoning about Gravity, Mass, Force and Motion
The purpose of this study was to examine whether force feedback within a computer simulation had an effect on reasoning by fifth grade students about gravity, mass, force, and motion, concepts which can be difficult for learners to grasp. Few studies have been done on cognitive learning and haptic …

Hydrodynamic drag force in liquids
… at constant velocity, the hydrodynamic drag force, D, is equal to the weight of the sphere, and the drag coefficient, CD, in the formula for the drag force, D = CD( 12rv2 )A could be evaluated as a function of Reynolds number, NR = rvah , and ball radius, a. In these formulas D is the drag …
