In physics, a force is any influence that causes a free body to undergo an acceleration. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. A force has both magnitude and direction, making it a vector quantity. Newton's second law, F=ma, can be formulated to state that an object with a constant mass will accelerate in proportion to the net force acting upon and in inverse proportion to its mass, an approximation which breaks down near the speed of light. Newton's original formulation is exact, and does not break down: this version states that the net force acting upon an object is equal to the rate at which its momentum changes.

Related concepts to accelerating forces include thrust, increasing the velocity of the object, drag, decreasing the velocity of any object, and torque, causing changes in rotational speed about an axis. Forces which do not act uniformly on all parts of a body will also cause mechanical stresses, a technical term for influences which cause deformation of matter. While mechanical stress can remain embedded in a solid object, gradually deforming it, mechanical stress in a fluid determines changes in its pressure and volume.

Philosophers in antiquity used the concept of force in the study of stationary and moving objects and simple machines, but thinkers such as Aristotle and Archimedes retained fundamental errors in understanding force, due to an incomplete understanding of the sometimes non-obvious force of friction, and a consequently inadequate view of the nature of natural motion. Most of the previous misunderstandings about motion and force were eventually corrected by Sir Isaac Newton; with his mathematical insight, he formulated laws of motion that remained unchanged for nearly three hundred years. By the early 20th century, Einstein developed a theory of relativity that correctly predicted the action of forces on objects with increasing momenta near the speed of light, and also provided insight into the forces produced by gravitation and inertia.

With modern insights into quantum mechanics and technology that can accelerate particles close to the speed of light, particle physics has devised a Standard Model to describe forces between particles smaller than atoms. 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.

How do I force a company that owes me money into an involuntary bankruptcy?
Q. A company owes me a substantial amount of money. I am their largest creditor. Their liabilities are significantly more than their assets. They refuse to make any payment arrangements. I want to force them into an involuntary bankruptcy. How and where do I begin the process of forcing them into bankruptcy? I am in the same state the company is in. Can I force a liquidation BK rather than a reorganization BK?
Asked by Michael M - Sun Dec 27 11:22:44 2009 - - 4 Answers - 0 Comments

A. Here is the information: The requirements are at the bottom. Just realize that if you are an unsecured creditor, that you are last in line for payout under a Chapter 7 bankruptcy, so explore the Chap. 11 first.

What is the gravitational force between a woman and earth?
Q. A 70 kg woman is standing on the Earth at a height of 2 meters. What is the gravitational force between the woman and Earth (Remember a=g=9.8m/s2)? How does this compare with the gravitational force between the woman and Jupiter (Hint R= the radius of Jupiter)? I know the gravitational formula but here is my question: Has G changed from the Universal gravitation constant to the one above: a=g=9.8m/s2? And what is R in this case? Is it just 2 or is it the radius of earth or both? Thanks.
Asked by LiveLuv&Laugh - Mon Mar 22 18:02:25 2010 - - 2 Answers - 0 Comments

A. It is her weight in newtons, in this case 70 x 9.8 = 686 Newtons. The gravitational force between the woman and jupiter will be very small, and it varies as the distance between earth and jupiter depends on their orbits. The radius of Jupiter has nothing to do with this. But perhaps you left out that the woman is on jupiter? lower case g usually means the acceleration due to gravity on earth, and is about 9.8 m/s Upper case G is the gravitational constant and is 6.673e-11 Nm /kg R can mean any number of things, depending on the problem. .
