Calculating Force - Spring Branch ISD
... Sir Isaac Newton expressed the relationship between force, mass, and acceleration in his second law. Newton’s contribution to science was so great that the unit for force, the Newton (N), was named after him. A Newton is defined as the force needed to produce an acceleration of 1 m/s2 on a 1 kg obje ...

... g = 0, but this is NOT true. If you stand on a scale in an elevator and then the cables are cut, you will also weigh nothing (ma = N – mg, but in free-fall a = g, so the normal force N = 0). This does not mean g = 0! Astronauts in orbit are in free-fall around the Earth, just as you would be in the ...

Modified Newtonian dynamics
In physics, modified Newtonian dynamics (MOND) is a theory that proposes a modification of Newton's laws to account for observed properties of galaxies. Created in 1983 by Israeli physicist Mordehai Milgrom, the theory's original motivation was to explain the fact that the velocities of stars in galaxies were observed to be larger than expected based on Newtonian mechanics. Milgrom noted that this discrepancy could be resolved if the gravitational force experienced by a star in the outer regions of a galaxy was proportional to the square of its centripetal acceleration (as opposed to the centripetal acceleration itself, as in Newton's Second Law), or alternatively if gravitational force came to vary inversely with radius (as opposed to the inverse square of the radius, as in Newton's Law of Gravity). In MOND, violation of Newton's Laws occurs at extremely small accelerations, characteristic of galaxies yet far below anything typically encountered in the Solar System or on Earth.MOND is an example of a class of theories known as modified gravity, and is an alternative to the hypothesis that the dynamics of galaxies are determined by massive, invisible dark matter halos. Since Milgrom's original proposal, MOND has successfully predicted a variety of galactic phenomena that are difficult to understand from a dark matter perspective. However, MOND and its generalisations do not adequately account for observed properties of galaxy clusters, and no satisfactory cosmological model has been constructed from the theory.
