Any action between two bodies which changes, or tends to change, their relative condition as to rest or motion; or, more generally, which changes, or tends to change, any physical relation between them, whether mechanical, thermal, chemical, electrical, magnetic, or of any other kind; as, the force of gravity; cohesive force; centrifugal force.

Anything that causes change, like a push is a force that causes an object to change.
An elementary physical cause capable of modifying the motion of a mass (pedaling your bike to make it go, throwing a baseball, pushing your brother out of your seat).
the cause, or agent, that puts an object at rest into motion or alters the motion of a moving object; an object's weight is a force that is brought about by it's mass and by gravity.
the push or pull that makes something move, slows it down or stops it, or the pressure that something exerts on an object. There are two types of forces - external and internal. To keep the form of an object, the internal forces must match the external forces. To make anything move (or change the way it moves) there has to be a force (push, pull or twist) acting on it.
Force is a measurement of physical exertion. Common units of force are Newtons and Pounds. Weight is a measurement of the force of gravity pulling down on an object.
Any action that tends to change the state of rest or of motion of a body to which it is applied. The unit of measure for the magnitude of force is Newton (poundforce).

That ability of energy that can change the state of rest or motion in matter.
The influence on a system of bodies that produces or tends to produce a change in shape, motion and/or other effects.

The four dominant forces within an oilfield are the viscous, pressure, gravitational and inertial forces.

(physics) the influence that produces a change in a physical quantity; "force equals mass times acceleration" www.cogsci.princeton.edu/cgi-bin/webwn The product of mass (m) and acceleration (a), measured in newtons (nt); thought of as the cause of motion in classical dynamics; that quantity which equals ma in Newton's equation of motion; e.g., gravitational force or the Lorentz force law. Newton's law of acceleration is used to derive the units of force. With the formula F = Ma in the cgs system, one dyne is the force needed for an acceleration of one centimeter per second per second with a mass of one gram. In the mks and SI systems, one newton is the force needed for an acceleration of one meter per second per second with a mass of one kilogram. One newton equals 105 dyne. To convert to English units, 1 N = 0.225 lb. www.wave-guide.org/library/glossary.html
A push or pull on an object. When an object is at rest, any force acting on it is balanced by an equal force in the opposite direction.
Energy exerted.
A force is a push or a pull acting upon an object. Forces result from interactions between two objects. Most interactions involve contact. If you hit the wall, the wall hits you back. The contact interaction between your hand and the wall results in a mutual push upon both objects. The wall becomes nicked (if hit hard enough) and your hand hurts. Bumper cars experience mutual forces acting between them due to contact during a collision. Some forces can act from a distance without actual contact between the two interacting objects. Gravity is one such force. On a free fall ride, there is a force of gravitational attraction between the Earth and your body even though the Earth and your body are not in contact.

1. A push or a pull. 2. Something that pushes or pulls on an object in a certain direction, measured in newtons.
Force is not visible but its effect is visible. Force is rate of change of momentum. Momentum is product of mass and velocity. Force = mass x acceleration. It has a direction and a magnitude. Unit is kg.m/sec2 . 1 kg = 10N.
The action of one body on another body which changes or tends to change its state of rest or motion. A force may be expressed in Kilo Newton(s) (kN), or other similar units.
A push or a pull in a certain direction, that can be measured. Examples of forces are your hand pushing on a doorknob, and a propeller pulling an airplane through the air.
Force is that which changes the state of rest or motion of a body. Strength; power,'energy' that causes or alters motion. "Body forces, and contact forces created through loading, are ultimately responsible for geologic deformation. These forces work through the 'undercover agent' known as stress."( Davis , G. H. and Reynolds, S. J.,1996.)
A push or a pull. The unit of force is the newton, N. Energy
A push or pull, which defined by Newton's Second Law of Motion. F=ma
The result of an event that produces pressure or causes an object of non-zero mass to accelerate. Everyday examples of force include a person pushing a door open, pulling a rope, or tightening a screw. There are four fundamental forces that cause such actions to happen: gravity, the electromagnetic force, the weak force, and the strong force. Gravity and the electromagnetic force are the two forces with which people are usually familiar; the weak force and the strong force apply to subatomic particles.
A vector quantity tending to produce an acceleration of an object in the direction of its application. Capacity to do work or cause physical change. A push or pull. A vector quantity possessing size and direction.

A force may be expressed in pounds (Newtons), kips, or other similar units and may act in any one of the following ways Compression force: A force acting on a body tending to compress the body, (Pushing action). Shear force: A force acting on a body which tends to slide one portion of the body against the other portion of the body. (Sliding action).
