From Wiktionary under the GNU Free Documentation License. In physics, a force is a push or pull that can cause an object with mass to change its velocity. Force has both magnitude and direction, making it a vector quantity. Newton's second law states that an object with a constant mass will accelerate in proportion to the net force acting upon and in inverse proportion to its mass. Equivalently, the net force on an object equals the rate at which its momentum changes. See also thrust. Forces acting on three-dimensional objects may also cause them to rotate or deform, or result in a change in pressure or even change volume in some cases. The tendency of a force to cause changes in rotational speed about an axis is called torque. Deformation and pressure are the result of stress forces within an object. Since antiquity, scientists have used the concept of force in the study of stationary and moving objects. However, descriptions of forces by Aristotle incorporated fundamental misunderstandings, which, despite advances made by the third century BC philosopher Archimedes from studies of simple machines, persisted for many centuries. By the seventeenth century, Sir Isaac Newton corrected these misunderstandings with mathematical insight that remained unchanged for nearly three hundred years. By the early 20th century, Einstein in his theory of general relativity successfully predicted relativistic adjustments to Newton's model for gravity by ushering in the concept of a space-time continuum. The recent theory of particle physics known as the Standard Model associate forces at the level of quantum mechanics. The Standard Model predicts that exchange particles called gauge bosons are the fundamental means by which forces are emitted and absorbed. Only four main interactions are known: in order of decreasing strength, they are: strong, electromagnetic, weak, and gravitational. High-energy particle physics observations made during the 1970s and 1980s confirmed that the weak and electromagnetic forces are expressions of a more fundamental electroweak interaction.

What would happen to the magnitude of the gravitational force between two bodies if the mass of one of the bodies were doubled? -The gravitational force would increase. What would happen to the magnitude of the gravitational force between two bodies if the distance were doubled? - The gravitational force would decrease. would these responses be correct? I'm assuming that since mass is proportional in the equation then an increase in mass would result in an increase in force. Since distance is inversely proportional, the doubling of distance would decrease the force. ? Asked by late.dawns - Thu Mar 19 01:19:23 2009 - - 1 Answers - 0 Comments A. You are correct. I will just note that it depends on the square of the distance so doubling the distance would decrease the force to 1/4 what it was originally.

The wagon weighs 150 N and is being pushed with a force of 5.0N, right. What is the net force acting on the block? Asked by ryan w - Thu Oct 25 10:31:33 2007 - - 2 Answers - 0 Comments A. the net force would be 0. when it is moving with constant velocity, there is no acceleration. since there is 0 acceleration, using the formula F=ma, net force(resultant force) will be equals to 0 also. Answered by freakinclown - Thu Oct 25 10:58:06 2007 How can I get into the Air Force and pick my job after getting honorable discharge from the Marines?
Q. I am an Infantrymen in the Marines, but also have done Security Forces my first 2 years and want to get into the Air Force and possibly pick my job. And would I be able to keep my paygrade of E4? I keep hearing that the Air Force isnt accepting any prior service members. Asked by Jon - Thu Apr 24 00:25:20 2008 - - 2 Answers - 1 Comments A. What you hear about the air force not accepting prior service is true.I was in his office and a marine called asking if he could join and he had to tell him no,their only accepting the best right now.I would suggest a asvab of 80 or greater.
