The Physics Classroom serves students, teachers and classrooms by providing classroom-ready resources that utilize an easy-to-understand language that makes learning interactive and multi-dimensional. Written by teachers for teachers and students, The Physics Classroom provides a wealth of resources that meets the varied needs of both students and teachers.
Physics is the basic physical science.Until rather recent times physics and natural philosophy were used interchangeably for the science whose aim is the discovery and formulation of the fundamental laws of nature. As the modern sciences developed and became increasingly specialized, physics came to denote that part of physical science not included in astronomy, chemistry, geology, and ...
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and elsewhere in the universe and ...
In the conceptual model of fundamental interactions, matter consists of fermions, which carry properties called charges and spin ± 1 ⁄ 2 (intrinsic angular momentum ± ħ ⁄ 2, where ħ is the reduced Planck constant).They attract or repel each other by exchanging bosons.. The interaction of any pair of fermions in perturbation theory can then be modelled thus:
where, F is the gravitational force between two bodies; m 1 is the mass of one object; m 2 is the mass of the second object; r is the distance between the centers of two objects; G is the Universal Gravitation Constant.; Henry Cavendish, with careful experiments, found the value of Gravitational Constant to be 6.67 x 10 −11 m 3 ⋅kg −1 ⋅s −2 N.The value of 'G' remains constant ...
The inspiration of Newton's apple is a part of worldwide folklore and may even be based in fact. Great importance is attached to it because Newton's universal law of gravitation and his laws of motion answered very old questions about nature and gave tremendous support to the notion of underlying simplicity and unity in nature.
If successful, it would certainly be a major step forward in physics: the ability to produce, detect and, ultimately, control gravitational fields. Source: Gravitation under human control? Physicist proposes using magnetic fields to produce and detect gravitational fields — ScienceDaily
Even though we have no tiered reward system set up, many of our students have selflessly donated to support ilectureonline. Thank you all for your generous support! There will be website maintenance coming in the near future; we'll post the scheduled times when they become available.
American interest in "gravity control propulsion research" intensified during the early 1950s.Literature from that period used the terms anti-gravity, anti-gravitation, baricentric, counterbary, electrogravitics (eGrav), G-projects, gravitics, gravity control, and gravity propulsion. Their publicized goals were to discover and develop technologies and theories for the manipulation of gravity ...
The ability to manipulate gravity. Sub-power of Fundamental Forces Manipulation. Opposite to Anti-Gravity Manipulation. User can create, shape and manipulate gravity, a natural phenomenon by which all matter is brought together, toward one another. If they exist, the user may be able to manipulate gravitons, hypothetical elementary particles that mediate the force of gravitation.
4 · The Department of Energy has awarded UCF physicist and assistant professor Li Fang a career grant of $785,000.. The award is part of the DOE's Office of Science's Early Career Research Program, which recognizes researchers for their promising work, early on in their careers.
Introduction. If you were born between 1930 something and 1960 you were a part of the ufo phenomenon that swept the world in the fifties. And many contemplated the idea of antigravity such as Thomas Townsend-Brown and before him Nikola Tesla and before him John Worrell Keely, who takes us to a place before any of us were born, the 1880's.. Keely's method of gravity control involved sympathetic ...
Apr 05, 2018· The force on the falling object is F = G * (Me * Mo)/(r^2) where Me is the mass of the Earth and Mo is the mass of the object. For the acceleration of the object because of this force you have a = F/Mo.

Every object in the universe attracts every other object. The gravitational force formula, also known as Newton's Law of Gravitation, defines the magnitude of the force between any two objects. The formula for the gravitational force includes the gravitational constant, which has a value . The unit of the gravitational force is Newtons (N).
Gravitation under human control? Physicist proposes using magnetic fields to produce and detect gravitational fields Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but one physicist has proposed just that in a new article.
What is the gravity equation? Use the following formula to calculate the gravitational force between any two objects: F = G * M * m / R². F stands for gravitational force. It is measured in newtons and is always positive. It means that two objects of a certain mass always attract (and never repel) each other;
Gravity (from Latin gravitas, meaning 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light —are brought toward (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.The gravitational attraction of the original gaseous matter ...
Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but Prof. André Füzfa of Namur University has proposed just that in an article published in the scientific journal Physical Review D. If followed, this proposal could transform physics and shake up Einstein's theory of ...
Projectiles In physics, any object moving freely under gravity is called a projectile . By moving freely it is assumed there is no air resistance or other external forces.
Graviton (Franklin Hall) is a fictional supervillain appearing in American comic books published by Marvel Comics.Created by writer Jim Shooter and artist Sal Buscema, he first appeared in Avengers #158, dated April 1977. Over the years he has mainly opposed the Avengers in their various incarnations. Originally a gravity researcher, Franklin Hall gains the ability to control gravity ...
The solution of the problem involves substituting known values of G (6.673 x 10-11 N m 2 /kg 2), m 1 (5.98 x 10 24 kg), m 2 (70 kg) and d (6.39 x 10 6 m) into the universal gravitation equation and solving for F grav.The solution is as follows: Two general conceptual comments can be made about the results of the two sample calculations above.

Explanation: . Given that Newton's second law is, we can find the acceleration by first determining the force. To find the gravitational force, use Newton's law of universal gravitation: We are given the constant, as well as the asteroid masses and distance (radius).
