  1. NEWTON’S LAW OF UNIVERSAL GRAVITATION AND IT’S APPLICATION

    Reporters : Araniego Cadavos Ruaza Lopez Elizar Toring
  2. Newton’s law of universal gravitation States that all objects in the universe attracts each other by the force of gravity.
  3. The size of the force depends on the two(2) factors: The masses of the objects The distance between them The force of gravity increases as the mass of object increases, Gravitational forces decreases as the distance between the objects increases.
  4. weight AND MASS Mass is a measure of how much material is in an object, but weight is a measure of the gravitational force exerted on that material in a gravitational field; thus, mass and weight are proportional to each other, with the acceleration due to gravity as the proportionality constant. It follows that mass is constant for an object (actually this is not quite true, but we will save that surprise for our later discussion of the Relativity Theory), but weight depends on the location of the object.
  5. a.) The weight of an object varies according to the force of gravity pulling on you and the force of gravity varies according to distance from center of the Earth. b.) Your mass does not, your mass is same anywhere on the Earth, on the Moon, and even on Jupiter. It is your weight that changes. Because of the great distance of an object to the Earth, it has less weight but it does not affect the mass.
  6. c.) According to Newton’s second(2nd) law: Force = mass*acceleration (can be rewritten in terms of weight) weight = mass * acceleration due to gravity Into an equation: N = Mass * 9.8 m/s/s or w = m * g Since the unit of weight is Newton(N) and unit of mass is kilograms, on the surface of the earth, the acceleration due to gravity is 9.8 m/s/s(9.8 m/s2).
  7. Sir Isaac Newton: The Universal Law of Gravitation application: What Really Happened with the Apple?
  8. Sir Isaac's Most Excellent Idea Now came Newton's truly brilliant insight: if the force of gravity reaches to the top of the highest tree, might it not reach even further; in particular, might it not reach all the way to the orbit of the Moon! Then, the orbit of the Moon about the Earth could be a consequence of the gravitational force, because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth.

  9. Kepler’s law of planetary motion

  10. Kepler's First Law: on Orbits Every planet moves in an elliptical orbit, with the Sun at one focus.
  11. Kepler's Second Law: on Areas As a planet moves in its orbit a line drawn from the Sun to the Planet sweeps out equal areas in equal time intervals. The line joining the two bodies (the sun and the revolving object) sweeps equal areas in equal times. The graphic precisely displays Kepler's second law. The area of every triangle formed is exactly the same area. Also notice as the planet or satellite moves closer to the sun, the speed of its orbit increases, but when it is located farther away from the sun, the speed in which the planet or satellite revolves around the sun is slower.
  12. Kepler's Third Law: on Periods It stated that if P is the period and M is the length of semimajor axis of a planet's orbit, then the ratio P²/M³ is the same for all the planets. Table  of values that verifies Kepler's third law.   The linearity of the line between the period and lenth of the semimajor axis verifies that relationship.
