The most familiar non-contact force is gravity, which confers weight. [1] In contrast, a contact force is a force which acts on an object coming physically in contact with it. [1] All four known fundamental interactions are non-contact forces: [2] Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on ...
Culminating point – The point at which a military force is no longer able to perform its operations; Decisive point – A geographic place, specific key event, critical system, or function that allows commanders to gain a marked advantage over an enemy and greatly influence the outcome of an attack
Fire and movement, or fire and maneuver, is the basic modern military low-level unit tactic used to maneuver on the battlefield in the presence of the enemy, especially when under fire. It involves heavy use of all available cover, and highly-coordinated exchanges of rapid movement by some elements of the squad or platoon while other elements ...
Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction force. [1] Not all forces are contact forces; for example, the weight of an object is the force between the object and the Earth, even though ...
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
Economy of force is the reciprocal of mass. No part of a force should ever be left without purpose. The allocation of available combat power to such tasks, like limited attacks, defense, delays, deception or even retrograde operations is measured, in order to achieve mass at decisive points elsewhere on the battlefield.
Action at a distance is the concept in physics that an object's motion can be affected by another object without the two being in physical contact; that is, it is the concept of the non-local interaction of objects that are separated in space.
The following outline is provided as an overview of and topical guide to military science: Military science – study of the technique, psychology, practice and other phenomena which constitute war and armed conflict. It strives to be a scientific system that if properly employed, will greatly enhance the practitioner's ability to prevail in an ...
