In this world there are four major forces that keep this earth in one piece. Those four forces would be that of: Strong Nuclear force, Weak Nuclear Force, Electro Magnet Force and lastly Gravity. Each of these unique forces are carried by a separate “messenger particle”, they don’t necessarily “carry” the forces, but help detect the particles as being active when they interact. Experiments c completed by scientist has proved the existence of three of the four forces, all except Gravity.

The first is The Strong Nuclear Force. The strength of this particle is very precise and particular. In order for the nucleus of this atom to be formed the protons and electrons need to be specifically arranged and be the correct distance apart. What the Nuclear Forces does is to keep the quarks together inside the protons and neutrons. Its messenger particle is the weightless “gleu” which holds the particles together.

Underneath The Strong Nuclear Force is The Weak Force or Weak Interaction. This maintains the balance of protons and neutrons in the atom. This insures that things in the atom run smoothly and do not abruptly fall apart or discharge any damaging radiation. While the stability of this atom is being kept by the Weak Interaction are able to transform and continue to exist.

The Electro Magnet Force works between electrically charged particles. This particular Force pretty much guarantees that opposites attract and don’t stray away from each other. While making sure that opposites attract he’s also making sure that the protons resist each other. The last and least known of the four fundamental forces of physics is gravity. Gravity is the weakest of the four forces. This force acts between all mass in the universe and has infinite range. Every object on this earth applies some type of gravitational force to everything around it. The messenger particle of this force is Graviton. What this helps the nucleus does is unclear for the reason...

In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. In other words, a force 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 a flexible object to deform, or both. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F.
The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.[1] If...

FUNDAMENTALFORCES OF NATURE
There are four fundamentalforces of nature that have been identified the universe, namely, Weak Force, Strong Force, Electromagnetic Force and Gravitational Force. They are found to have rather different properties and play central roles in making the universe what it is today.
Weakforce is a force between elementary particles that causes certain processes that take place with low probability, as radioactive beta-decay and collisions between neutrinos and other particles. Neutrinos interactions are created as a result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. Radioactive decay is spontaneous disintegration of a radionuclide accompanied by the emission of ionizing radiation in the form of alpha or beta particles or gamma rays.
Strong interaction is a fundamental interaction between elementary particles that causes protons and neutrons to bind together in the atomic nucleus. Also called strong force. The strong force is a short-range attractive force between baryons that holds together the nucleus of the atom.
Electromagnetic force is the...

generally make themselves felt by means of the exchange of a mediating particle; the particle that mediates the electromagnetic field, for example, is the photon, or quantum of light. The mediating particles of the gravitation al field, the weak field and the strong field are respectively the graviton (which has not yet been detected), three weak vector bosons, called the W+, W- and ZO particles, and eight gluons. In a somewhat analogous way the Higgs boson is the mediating parti cle of the proposed Higgs field. It is now assumed that there is a con stant Higgs field throughout all space, that is, the vacuum of outer space is not empty but contains this constant field. The Higgs field is thought to gen erate mass by coupling to particles. Depending on the coupling strength, a particle in space has a certain potential energy. By Einstein's famous equa tion, E = mc2 (energy equals mass multiplied by the square of the speed of light), the coupling energy is equiva lent to a mass. The stronger the cou pling, the greater the mass. The way particles are thought to ac quire mass in their interactions with the Higgs field is somewhat analogous to the way pieces of blotting paper ab sorb ink. In such an analogy the...

...HYDROSTATIC FORCE (EXPERIMENT 1)
INTRODUCTION
The determination of force which are exerted by liquid which are at rest on surface immersed in liquids. From the study by hydrostatic, the following principles have been established :
a) There are no shear stress present when the fluid is not in motion.
b) The pressure exerted by a fluid under hydrostatic conditions. This pressure acts perpendicular to an immersed surface.
c) Hydrostatic pressure various linearly, increasing with an increase in depth.
OBJECTIVES
1. To determine the hydrostatic thrust on a plane surface partly immersed in water.
2. To determine the position of the line of action of the thrust.
3. To compare the position determined by experiment with the theoretical position .
4. To verify the formula for calculating hydrostatic thrust.
THEORY
When the quadrant is immersed in water it is possible to analyze the forces acting on the surfaces of the quadrant as follows:
The hydrostatic force at any point on the curved surface is normal to the surface and therefore resolves through the pivot point because this is located at the origin of the radii. Hydrostatic forces on the upper and lower curved surfaces therefore have no net effect – no torque to affect the equilibrium of the assembly because all of these forces pass through the pivot.
The forces on the sides of the...

...Definition of Force
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces onlyexist as a result of an interaction.
Velocity, Acceleration, Momentum, and Impulse
Velocity, in physics, is a vector quantity (it has both magnitude and direction), and is the time rate of change of position (of an object). However, quite often when you read ‘velocity’, what is meant is speed, the magnitude of the velocity vector (speed is a scalar quantity, it has only magnitude). For example: escape velocity (the minimum speed an object needs to escape from a planet, say); note that this can be easily turned into a velocity, by adding ‘in the direction radially out from the center of the planet’, and that this direction is sometimes implied (if not actually stated).
Velocity is a vector measurement of the rate and direction of motion or, in other terms, the rate and direction of the change in the position of an object. The scalar (absolute value) magnitude of the velocity vector is the speed of the motion. In calculus terms, velocity is the first derivative of position with respect to time.
The most common way to calculate the constant velocity of an object moving in a straight line is with...

...Force & Motion
Isaac Newton – English physicist & mathematician.
Newton’s First Law of Motion(Law of Inertia):
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalance force.
An object at rest tends to remain at rest. An object in motion tends to move at a constant speed in a straight line unless acted upon by an unbalanced externalforce.
Newton’s Second Law of Motion(Law of Acceleration):
An object’s acceleration is directly proportional to the net force acting on it and is inversely proportional to the object’s mass.
Newton’s Third Law of Motion(Law of Interaction):
For every action, there is always an equal and opposite reaction.
Force is any interaction which tends to change the motion of an object. It can also be described by intuitive concepts such as a push or pull.
Unbalanced Forces
An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
Direct proportion- means that when one factor increases, the other factor also increases and vice versa.
Inverse proportion- means that when one factor increases, the other factor decreases.
Acceleration- increase in the rate or speed of something....

...How competitive forces shape strategy Pﬂicht 4. (5Forces)

1 von 3
While one some- times hears executives complaining to the contrary, intense competition in an
industry is neither coincidence nor bad luck.
Moreover, in the fight for market share, competition is not manifested only in the other players.
Rather, competition in an industry is rooted in its underlying economics, and competitive forces
exist that go well beyond the established combatants in a particular industry. Customers,
suppliers, potential entrants, and substitute products are all competitors that may be more or less
prominent or active depending on the industry.
- The weaker the forces collectively, however, the greater the opportunity for superior
performance.
T-he strongest competitive force or forces determine the profitability of an industry and so are of
greatest importance in strategy formulation.
There are six major sources of barriers to entry:
1. Economies of scale
—These economies deter entry by forcing the aspirant either to come in on a large scale or to accept
a cost disadvantage.
2. Product differentiation
Brand identification creates a barrier by forcing entrants to spend heavily to overcome customer
loyalty.
—> e.g. Softdrink Company
3. Capital requirements
The need to invest large financial resources in order to compete creates a barrier to entry
4. Cost disadvantages independent of size...
