Force :
Force is any action that tends to maintain or alter the position of a body or to distort it. The concept of force is commonly explained in terms of Newton's three laws of motion set forth in his Principia Mathematica (1687).
* - the relative strength column shows how each force compares to the Strong Nuclear Force - how many times weaker they are actually.

Forces are always produced in pairs, with opposite directions and equal magnitudes. If body #1 acts with a force F on body #2, then body #2 acts on body #1 with a force of equal strength and opposite direction.
Force multiplication, in military usage, refers to a combination of attributes or advantages which make a given force more effective than another force of comparable size....

Accelerations, and Forces
In order to understand the discoveries of Newton, we must have an understanding of three basic quantities: (1) velocity, (2) acceleration, and (3) force.

FORCE - That which produces acceleration. Intuitively, a push or a pull, an action of one thing upon another. Forces produce palpable effects. There are only four fundamental forces (q.v.).

(a) Agency responsible for a change in a system. In Newtonian mechanics, gravitational force bends the moon away from the straight trajectory it would otherwise pursue.

g-force
Units of g, or "gee," are used in aerospace when describing loads on aircraft or spacecraft. Someone who carried out remarkable experiments (on himself) involving very high g-forces was the pioneering aerospace physician John Stapp.

Real force. See: inertial frame.
Real image. The point(s) to which light rays converge as they emerge from a lens or mirror. See: virtual image.
weak force: One of the four forces of nature; the weak force is responsible for some forms of radioactive decay.
west point: The point on the western horizon exactly halfway between the north point and the south point; exactly west.
tidal force
the difference in gravitational force between two points on an object caused by the gravity of another object; the tidal force often leads to a deformation of an object

Elite ForceEdit
One of the mods made for the popular Star Trek: Voyager: Elite Force game is the "NX-01 Mod". The mod is set during an episode of Enterprise, and uses voice clips from the show for its cut scenes.
tidal force
The force exerted on an object by the body around which it is orbiting, due to the gravitational pull on the near face of the object being much stronger than the far side.
Tidal forces
the gravitational pull on planetary objects from nearby planets and moons.
TIDAL FORCES
Tidal forces are the gravitational pull exerted upon planetary objects by nearby planets, moons, or stars.
Force (F) equals change in velocity (acceleration, A) times mass (M):
F = MA
Acceleration may be produced by applying a force to a mass (such as a spacecraft).
Forces. It is commonly held that there exist certain forces, independent of spiritual beings or agencies, and also distinct from forces as defined by science (e.g., gravitation, electro-magnetism, etc.).
force Action of an object that causes momentum to change. The rate at which the momentum changes is numerically equal to the force.
frequency The number of wave crests passing any given point in a given period of time.
Force-carrying particles of nature. Three vector bosons are responsible for the weak nuclear force. By admitting the photon on an equal footing it is possible to create a unified electroweak theory.
Force of gravity at "surface"*

force - (n.)
in physics, something that can or does cause a change of momentum, measured by the rate of change of momentum with time.
force field - (n.) ...
A force field generated by moving electrical charges. An electrical current running through a loop of wire generates a magnetic field. The strength of the field depends on the current and area of the wire loop.

As force is required to accelerate a mass (change it's velocity) in a linear fashion, torque is required to accelerate something in a rotational fashion (change it's rotational or angular velocity).
The force exerted on the surface of a body by its absorption of light. Small particles floating in the solar system can be blown outward by the pressure of the sun-light.

The force which pulls any two (or more) objects together. It is inversely proportional to the square of the distance of the objects, and is what keeps the planets, asteroids etc orbiting the Sun.

The force exerted by the Moon on the Earth is having a similar effect on the Earth's rotation. Gradually the Earth is slowing down. One day, the length of time the Earth takes to spin round its axis will be the same as the Moon takes to orbit us.
The force that governs the change of one kind of elementary particle into another. This force is associated with radioactive processes that involve neutrons.

Tidal forces affecting the Oort cloud come from stars in the Milky Way's galactic disk with some pull from the galactic core. The tide results from the sun and comets being different distances from these massive amounts of matter.
Tidal forces cause orbits to go to a state of lowest energy while conserving angular momentum. This results in the circularization of originally elliptical orbits. The ocean tide on earth from moon is

CORIOLIS FORCE
The Coriolis force is the force that results from the rotation of the Earth around its axis; it makes storms rotate counterclockwise in the Northern and clockwise in the Southern Hemispheres.
repulsive force that opposes the self-attraction of matter (see gravitation) and causes the expansion of the universe to accelerate.
The tidal force from Jupiter, on the other hand, works to circularize their orbits.
Aerodynamic forces on the lifting surfaces (for example, the wings) of an aircraft keep it aloft against the force of gravity, but a space vehicle cannot stay aloft in this way because of the absence of air in space.

These tidal forces significantly heat the two innermost Galilean moons. The gravitational pull of the mother planet and sister moons constantly yank and bend Io, heating it up in the same way repeated twisting heats up a metal wire.
The residual force just described is not limited to the case of an ellipsoidal body.
Voyager 2 was forced to fly close to Uranus in order to get the boost it needed to go on to Neptune and due to the orientation of the whole system at almost right angles to the ecliptic only Miranda was approached closely.
describes the force of gravity between two objects of mass M and m and separated by a distance R (the term G is a constant that relates the units of mass and distance to those of force).
