What are the different types of mathematical relationships?
The three attached graphs highlight the relationships between force, mass Although mathematically, this would make sense, since adding mass makes the. Hyperbolas consist of two vaguely parabola shaped pieces that open either up and down or right and left. Also, just like parabolas each of the pieces has a. The hyperbola is the least known and used of the conic sections. the same relation to the hyperbola as the circle bears to the ellipse. . Alpha particles are the nuclei of helium atoms, with mass 4 and a positive charge of 2e.
The least known and appreciated of the conic sections has some interesting applications nevertheless Definition of the Hyperbola The hyperbola is the least known and used of the conic sections. We seldom see a hyperbola in daily life, and it seldom appears in decoration or design.

In spite of this, it has interesting properties and important applications. There is a literary term, hyperbole, that is the same word in Greek, meaning an excess. How the hyperbola acquired this name is related in Parabolatogether with some general information on conic sections, and the focal definition of the hyperbola.
The feature of the hyperbola is its asymptotes. This is, of course, in a certain direction along the line that extends to infinity.Introduction to Hyperbolas
A hyperbola has two asymptotes that make equal angles with the coordinate axes and pass through the origin O. Near the origin, the hyperbola passes from one asymptote to the other in a smooth curve. There are two branches of the hyperbola, starting from opposite ends of the asymptotes. For most practical purposes, the hyperbola can be considered as the asymptote itself except in the neighborhood of the origin. A hyperbola is sketched at the right.
The origin is O, and the asyptotes form a symmetrical cross as shown. V and V' are the vertices of the hyperbola, at a distance a on each side of the origin. Perpendicular lines from V and V' define a rectangle by their points of intersection with the asymptotes, and the sides of this rectangle are a and b. Two parameters are required to specify a hyperbola, as for an ellipse. If you draw the reference rectangle for the hyperbola, the foci can be located quite simply by swinging an arc.
The difference in the distances F'P and FP from the foci to any point P on the hyperbola is equal to 2a. It is not difficult to prove that this definition is equivalent to the canonical equation. Moreover, as the sketch indicates, the angle between FP and the normal to the hyperbola is equal to the angle between the normal and F'P, so a ray from F is reflected by the hyperbola so that it appears to be coming from the other focus.
This is the analogue to the reflecting properties of the parabola and ellipse. As the other conic sections, the hyperbola has conjugate diameters.
To exhibit them, we need the conjugate hyperbola, which is constructed on the same reference rectangle. Its foci F''' and F"" are the same distance c from the origin, so all four foci lie on a circle.
Of course, the asymptotes are the same. A diameter, such as AB, is any line passing through O that intersects the two branches of the hyperbola. The conjugate diameter CD is drawn between the points of tangency of lines parallel to the diameter that touch the conjugate hyperbola. The conjugate diameter bisects all these chords it does not seem so in the sketch, because the curves are not accurate.
This property may be used to construct normals and tangents as an alternative to the focal property. Finally, a hyperbola is the intersection of a cone really, a double cone extending in both directions with a plane with an inclination greater than the cone angle.
The draftsman is not often required to draw hyperbolas. It is easiest to draw one from the focal definition. An arc is drawn from F with any radius r, and this is intersected by an arc drawn from F' with radius r - 2a.
It is easy to locate the foci when a and b are given, so this process is convenient. The intersections are good near the origin, but become poor farther out on the asymptotes. However, they are not needed here. This is called the equilateral hyperbola, and all these curves are the same shape, differing only in size.
Other examples of this relationship can be found. Unlike circles, equilateral hyperbolas are not good wheels, and are not as easy to draw. If one point P is known on an equilateral hyperbola, another P' can be found by the construction sketched at the right.
The intersection of the horizontal through B and a vertical line through C determines the second point P'. Two parallel glass plates in contact at the left, and separated by about 5 mm at the right, are dipped in beet juice, which rises by capillarity to form an equilateral hyperbola. The positive, linear slope shows that there is a direct, linear relationship between acceleration and force.
This agrees with the mathematical equation, since a constant mass is being divided into a larger numerator, or force, acceleration should increase. These differences could be attributed to two factors: To increase applied force, we had to increase the mass of the system. Although by comparison, the additional mass was small, it never the less impacted our data.
Our observations show that both force and mass affect acceleration. Additional mass decreases acceleration and increasing the applied force increases acceleration. Example of an inverse relationship in science: When a higher viscosity leads to a decreased flow rate, the relationship between viscosity and flow rate is inverse. Inverse relationships follow a hyperbolic pattern.
Below is a graph that shows the hyperbolic shape of an inverse relationship. Quadratic formulas are often used to calculate the height of falling rocks, shooting projectiles or kicked balls. A quadratic formula is sometimes called a second degree formula.

Quadratic relationships are found in all accelerating objects e. Below is a graph that demostrates the shape of a quadratic equation. Inverse Square Law The principle in physics that the effect of certain forces, such as light, sound, and gravity, on an object varies by the inverse square of the distance between the object and the source of the force.
In physics, an inverse-square law is any physical law stating that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space.
One of the famous inverse square laws relates to the attraction of two masses. Two masses at a given distance place equal and opposite forces of attraction on one another.
The magnitude of this force of attraction is given by: The graph of this equation is shown below. More on Brightness and the inverse square law Damping Motion Damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its oscillations. In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation.
