Introduction:
This portfolio will investigate how to create an equation that has a line of best fit for a given set of data. The points given will be plotted to see if there is a recognizable regression formed. In order to find the right regression equation, different regression equations will be tested with the data points provided. The process of finding the right equation and the testing of points will be provided. Each set of points and equations formed will include a graph. Once the best equation is formed it shall be tested to see if it fits the next set of data points. Once plotted, comments shall be made.

Horizontal G-Force:
Here is a table of horizontal G-force tolerance in humans. “+Gx” represents the horizontal acceleration, which means +Gx of 11 means that at 1 minute, humans can tolerate a horizontal acceleration of 11. + Gx (g) (x)| Time (min) (y)|

The data is arranged from highest force/lowest time, to lowest force/highest time. By looking at the chart, humans can withstand a lower G-force for longer periods of time. As time increases, the G-Force (or horizontal acceleration) decreases, and vice versa. These points were plotted on a graph where acceleration is the x axis, and time is the y axis. There are only 8 points represented which may not be an accurate regression. Since the values are not spaced out in even intervals, so the graph cannot be linear.

The data seems to create an asymptote when the force reaches 35. It makes sense that humans tolerate a lower force for a longer time, and a higher force for a shorter period of time. It can be assumed that as the force or +Gx increases, time will decrease. This graph looks similar to an exponential graph, so a function will be created to see if an exponential function most accurately fits this graph.

...In every industry, there is a model that can be used to identify the strategy, profitability, and power of particular companies. This model is called the five forces model. This gives an analysis of companies for competing and personal uses. The five forces model consists of two major parts. The first part of the model consists of rivalry among existing firms, threat of new entrants, and threat of substitute products. This part measures how much actual and potential competition there is. The second major part is between the bargaining power of buyers and the bargaining power of suppliers. These two measure the power a company has or does not have over the buyers and suppliers. In using this model, we will be able to identify these valuable parts of Procter & Gamble.
Rivalry Among Existing Firms
With a high industry concentration, relatively low switching costs, large economies of scale benefits, and possible high exit costs, rivalry among existing firms in the personal products industry tends to be high.
Threat of New Entrants
There are many different barriers in the personal products industry that a new
entrant would have to overcome to enter. The large companies have a huge competitive advantage over new entrants that leave new entrants with little success in gaining any market share. With established economies of scale, access to distribution, relationships, and legal barriers in the favor of existing firms in the industry, a new...

...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....

...IB PHYSICS HL
Lab: Centripetal Force
BACKGROUND/PURPOSE:
*In this section of your lab write-up, be sure to include all equations and
background information
-For motion along a straight line, a constant net force F acting on a body of mass m produces a constant acceleration a, related to the force through Newton's law:
F = ma
-When the same object is moving in a circle at a constant speed, the acceleration of the object is given by the following equation:
a = v2/r
-In this experiment, you will use these two equations and some simple measurements to determine the unknown mass of a rubber stopper as it rotates in a horizontal circle around a fixed center point.
PROCEDURE:
The equipment that you will use is as follows:
-Glass tube
-Rubber stopper
-String
-Hanging masses (washers)
When the glass tube is swung in a small circle above your head, the rubber stopper moves around in a horizontal circle at the end of a string. The string is threaded through the tube and fastened to some washers hanging below. The force of gravity on these washers, acting along the string, provides the centripetal force needed to keep the stopper moving in a circle.
Before taking any measurements, get a feel for the apparatus. With only one washer on the end of the string to keep the stopper from getting away, whirl the stopper over your head while holding onto the string below the tube.
The mass of the stopper...

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 the mass of...

...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...
