Misconceptions about tides. Tidal forces are vector quantities, and may be drawn as arrows in a diagram, but the interpretation of such a diagram is different from that of a diagram of the gravitational forces themselves. It turns out that when this is done, the centrifugal force on a mass anywhere on or within the earth is of constant size, and is therefore equal to the size of the gravitational force the moon exerts on the same amount of mass at the center of the earth. Gravitational forces due to the moon, gravitational forces due to the earth, and tensile forces of materials are the only real forces acting on the material of the earth. www.lhup.edu /~dsimanek/scenario/tides.htm   (8855 words)

Tide - Wikipedia, the free encyclopedia The loss of rotational energy of the earth, due to friction within the tides, and the gravitational effects caused by tidal deformations of the earth's body, are responsible for the slowdown of the earth's rotation and the increase of the distance to the moon, see Tidal force. Ignoring external forces, the ocean's surface defines a geopotential surface or geoid, where the gravitational force is directly towards the centre of the Earth and there is no net lateral force and hence no flow of water. Gravitational forces follow the inverse-square law (force is inversely proportional to the square of the distance), but tidal forces are inversely proportional to the cube of the distance. en.wikipedia.org /wiki/Tides   (3430 words)

Vibrations - Gravitational Forces The latter acceleration is due to the gravitational attraction between the earth and the ball bearing and is so much larger because it varies directly with the mass of the source of attraction (i.e. Gravitation is the dominant force that keeps the planets in their orbit around the sun and the stars in their motion about the centre of the galaxy. Due to the masking effects of competing influences and the weakness of gravitation compared with the electromagnetic interactions the threshold for the detection of expected gravitationally induced signals remains tantalisingly close to the limits set by currently technology. www.lancs.ac.uk /depts/physics/vibrations/vib3.htm   (577 words)

Gravitational and Electrical forces Linked   (Site not responding. Last check: 2007-11-03) Chapter twelve derived gravitational forces in terms of the quantity of a continuous non-quantized form of mass contained a curvature or "depression" in a "surface" of a three-dimensional space manifold with respect to a fourth "spatial" dimension caused by a rotation of a continuous non-quantized form of mass. Since, as mentioned earlier the rotational energy of a continuous non-quantized form of mass is responsible for electrical energy the equation F=(E/c^2)^2/r^2 would define the ratio of the magnitude of gravitation force to the magnitude of the electrical energy associated with a rotation of a continuous non-quantized form of mass. This method does not give the exact value of 1/(417 X 10^42) for “the ratio of the gravitational attraction to electrical repulsions" because a portion of the mass associated with a gravitation field is diverted support the rotational energy of the continuous non-quantized form of mass responsible for an electric charge. home.comcast.net /~jeffocal/chapter14.htm   (701 words)

Relative Gravitational Forces   (Site not responding. Last check: 2007-11-03) shows the gravitational force each planet exerts on the earth relative to the moon's attraction. Namely, the gravitational force is proportional to the products of the bodies' masses and inversely proportional to the distance between them squared. This is easily refuted by considering the changes in the moon's gravitational force during its orbit around the earth. drumright.ossm.edu /astronomy/forces.html   (506 words)

Method and apparatus for simulating gravitational forces on a living organism - Patent 4421109 A method and apparatus for simulating gravitational forces on a living organism wherein a series of negative pressures are externally applied to successive lengthwise sections of a lower limb of the organism, the pressures decreasing progressively with distance of said limb sections from the heart of the organism. A method of simulating aspects of gravitational forces on at least a portion of a living organism comprising applying a series of negative pressures externally to successive lengthwise sections of a lower limb of said organism, said pressures decreasing progressively with distance of said limb sections from the heart of said organism. Several prior devices are known for simulating gravitational forces by applying a negative pressure to the lower portion of the body of a person. www.freepatentsonline.com /4421109.html   (6001 words)

Reduction of inertia and gravitational forces   (Site not responding. Last check: 2007-11-03) V/m, is capable of compensating for the gravitational force of the earth. It turns out that a 35 % change in the force of gravity on the average, results in the annihilation of electrons and positrons arising at dipole break, which is observable as radiation around the rotor. Simultaneously with the effects of luminescence and change of gravitational force there is a reduction in rotor inertia. www.laboratory.ru /articl/hypo/eax050.htm   (666 words)

BOEHM It is derived that gravitational forces are of electrodynamic nature and have their origin in nuclear electric displacement charges due to inertial matter motion. The universal gravitation constant G determined experimentally on Earth by using horizontal gravitational forces is claimed (as already mentioned) to be not applicable directly for the determination of any cosmic mass, since cosmic objects have all different velocities with respect to their central bodies. The known gravitation constant G is hypothesized to be not applicable directly to analyse central gravity forces for deriving masses of cosmic objects. www.physical-congress.spb.ru /english/boehm98/boehm.asp   (3982 words)

A New Look At Gravity That is, the force of gravity is proportional to the mass of an object. The answer to this mystery is that the gravitational force of the Sun has two components -- one due to the normal mass which comprises the Sun, and a second component caused by super-gravitational free nuclei within its core. It is known that light emitted by an object with a gravitational field experiences a redshift due to the influence of the gravitational forces. www.geocities.com /newastronomy/a_new_look_at_gravity.htm   (2690 words)

Gravitational Forces The objective of this lesson is for students to be familiar with Sir Isaac Newton, the development of his Law of Universal Gravitation. Students should be able to complete quantitative calculations using the Law of Universal Gravitation, understand the proportional nature of the equation, and be able to distinguish between mass and weight. This serves as an introduction to their next area of study: gravity, the weakest of the forces. www.gsu.edu /%7Emstjrh/gravity.html   (749 words)

Gravity Gravity, the ‘mystery force’, which is poorly understood after nearly four centuries of research, is one of the manifestations of this awesome divine upholding. The main danger to an astronaut near a fl hole is tidal forces, caused by the fact that gravity is stronger on the parts of the body closer to the fl hole than on the parts away from it. Gravitational time dilation at and near an event horizon is the basis of the new cosmological model of the creationist nuclear physicist Dr Russell Humphreys, in his book Starlight and Time. www.answersingenesis.org /creation/v22/i3/gravity.asp   (1944 words)

Chapter 21. Inertia IS Gravity The gravitational and electromagnetic forces are the long-range (extranuclear) ones, while the strong and weak forces are the short-range (intranuclear) ones. A non-gravitational force that is applied to an MO counteracts that portion of the MO's gravitational-force vector that is equal in magnitude to it but opposite in direction. The big MO's gravitational "pull" on the small MO is part of the small MO's gravitational-force-vector sum, which also includes the "pulls" of gravity (what we call "inertial force") from the rest of the MOs in the universe. www.writword.com /unituniv/c21.htm   (1694 words)

Forces There are for example, the forces that keep the cells together to build up the human body, and there is the gravitational force that keeps us on the ground and the moon in orbit around the earth. Since there were only two basic forces known in the beginning of the 20th century, gravitation and electromagnetism, and it was seen that electromagnetism is responsible for the forces in the atom, it was natural to believe that it was also responsible for the forces keeping the nucleus together. The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei. nobelprize.org /physics/articles/brink   (4640 words)

The Accelerating Universe as a Consequence of Decreasing Gravitational Forces The Accelerating Universe as a Consequence of Decreasing Gravitational Forces As the relative decrease of Newton's gravitational 'constant' is not lineary, this is also not the case for the increase in distance between the two systems in question. For instance the gravitational shift of wavelength is dependent on the strength of the gravitational field in the area from which the light is emitted. www.rostra.dk /louis/quant_16.html   (1239 words)

James Whinnery - near-death experiences from gravity Acceleration of gravitational stress is a unique aspect of flying fighter aircraft during aerial combat maneuvering. At the end of this period, consciousness is lost, and the gravitational stress is reduced back to normal conditions. The length of the unconsciousness averaged 12 seconds with a -5 to +5 standard deviation and a range of 2 to 38 seconds. www.near-death.com /experiences/triggers06.html   (1016 words)

Secrets of Vastushastra Since human consciousness has a direct relationship with the house occupied by the individual, this affinity of the house and the dweller is amplified to predict the eventualities for the house and the person on the basis of logical fibre of Astrology and Vastushastra. In Vastu Purush Mandal, two sources of energies or cosmic forces are designated by symbolic nomenclature which refers to the positive or negative confluence of these forces leading to positive, conformable and lively results, or negative, retrograde and destructive results as symbolised by the names of deities ruling various directions in Vastu Purush Mandal. Pranic or the solar force field can be represented as an everchanging dynamic vector referenced to solar position and moves through 360 degrees in relation to the earth's position. www.clairvoyanthealing.com /secretsofvastushastra/page01.htm   (680 words)

Ratio of Electric to Gravitational Forces   (Site not responding. Last check: 2007-11-03) The law of universal gravitation says that the force due to gravitational interaction between tow particles is proportional to the product of their masses divided by the square of the distance between them. From electrostatics we know that the force due to the electric interaction between two charged particles is proportional to the product of their charges divided by the square of the distance between them. The significance of the huge ratio between electric and gravitational forces is that in our chosen system of units, the unit electric charge is much more effective at distorting the space around them than is the unit mass. www.mcasco.com /qa_regf.html   (267 words)

Bending Spacetime in the Basement The stark difference in the strength of the electromagnetic and gravitational forces is evident in the picture to the left. When measuring the gravitational constant one must precisely calibrate the torsional strength of the fibre, but to simply observe gravitation we need only make sure the fibre is sufficiently limp to allow the gravitational force to overcome its resistance to twisting. Using the gravitational force calculator earlier in this document, we can compute the gravitational attraction between the 338 gram mass at the end of the balance beam and the 740 gram test mass at the 14 cm distance when the beam is at the midpoint between the masses to be 0.000085 dynes. www.fourmilab.ch /gravitation/foobar   (5823 words)

Gyroscopes - Everything you needed to know When a force applied to a gyroscope tends to change the direction of the axis of rotation, the axis will move in a direction at right angles to the direction in which the force is applied. T he identity between gravitational mass (measured by attractive force) and inertia (measured by acceleration) is a cornerstone of physics. According to this theory, local properties of inertia and gravitation are the result of the entire mass of matter in the universe and the space in which it exists. www.gyroscopes.org /glossary.asp   (1241 words)

Einstein's Gravitational Metrics After all, if we cannot distinguish between gravitational and non-gravitational accelerations and forces, we can do away with gravitational forces and their bothersome action-at-a-distance and claim that non-gravitational forces, or even Riemann's curved geometry, describe reality. While Einstein's principle of equivalence is confirmed by non-relativistic Newtonian experiments proving the equality of gravitational and inertial masses, equation (1) says it cannot be confirmed by relativistic experiments because these are expected to show the inequality of gravitational and non-gravitational accelerations and forces. At these speeds, we can distinguish between gravitational and non-gravitational accelerations and forces, and we can no longer do away with gravitational forces and their bothersome action-at-a-distance and claim that non-gravitational forces, or even Riemann's curved geometry, describe reality. www.coolissues.com /gravitation/gmetric.htm   (1263 words)

Bay of Fundy Tides - What causes these high tides? Commanded by the gravitational forces of the sun and moon, these Bay of Fundy tides, the highest tides in the world, can rise and fall over 16 meters (50 feet) in extreme circumstances. Although, because of its size, the sun exerts a gravitational force 180 times stronger than the moon, the moon is much closer, so its force across Earth's diameter is twice as strong as the sun's. As the moon exerts its force on the Earth, both the Earth and its waters respond by accelerating toward the Moon; however, the fluid waters on the side facing the Moon, being closer to the gravitational force, accelerate more and fall ahead of Earth. www.thehopewellrocks.ca /english/fundytides2.htm   (495 words)

Tidal Forces The force of gravity caused by an object gets weaker as you move farther away from that object. Because the gravitational force on one side of the planet is different from that on the other side, it is called a tidal force. Because planets are not perfectly rigid, they deform when subjected to such tidal forces (Earth also bulges at the equator all the way around because it is spinning). www.windows.ucar.edu /cgi-bin/tour_def/glossary/tidal_forces.html   (262 words)

Science: Physics - Cyclopedia.ws Now physics is concerned with all aspects of nature, covering the behavior of objects under the action of forces (basically the study of how matter moves around and interacts with other matter in Space). Of the four known forces, gravitational and electromagnetic are long range (act across the universe), and Strong and Weak nuclear forces are short range (10^-15m) and are used to explain nuclear interactions. What we observe as material bodies and forces are nothing but shapes and variations in the structure of space. cyclopedia.ws /home.aspx/Science/Physics   (721 words)
