PPT-Newton’s Universal Law of Gravity

Every object attracts every other object with a force that is directly proportional to the masses of the objects and inversely proportional to the square of the distance between the centers of the objects.

Newtonian Gravity. Newton explains the universe using forces. 2. Newton. Newtonian gravitational theory is based on forces acting on one another.. An object at rest stays at rest and an object in motion stays in motion (in a straight line) until acted upon by another force.. 4. – Newton and Einstein. ASTR 101. Prof. Dave Hanes. Newton . Succeeds!. The orbit of (newly-discovered) Uranus. Halley. ’. s comet (and others, later). The prediction of Neptune. The prediction of Pluto . Motion. Lesson 15. February 8. th. , 2011. Newton’s Second Law of Motion. If the external force on an object is not zero, the objet accelerates in the direction of the net fore. The magnitude of the acceleration is directly proportional to the net force and inversely proportional to the objects mass. . ASTR 101. Prof. Dave Hanes. Orbiting Near, Around, . and Away from the Earth. Let’s consider:. Ballistic missiles on Earth. Artificial satellites. Geosynchronous satellites. Actually escaping the Earth. Isaac Newton (1642-1727). Galileo found that bodies with different masses experienced the same acceleration when dropped to the ground. But he didn’t know why.. Kepler. discovered that the motions of the planets were perfectly reproduced by 3 mathematical relations. Like Galileo, . Honors Physics . Zero Gravity Cats!. Universal Gravitation. ALL. objects attract each other with a force of gravitational attraction. Gravity is universal. . This . force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. . Astronomy, Chapter 2. D Taylor. © 2011, 2012, 2013,2014. Gravity and Motion. 2. Introduction. Gravity. gives the Universe its structure. It is a universal force that causes all objects to pull on all other objects everywhere. In the mid-1500s, scientists begin to question accepted beliefs and make new theories based on experimentation. The Roots of Modern Science. The Medieval View. Most knowledge in the Middle Ages comes from the Bible and Greek/Roman sources.. kindly visit us at www.nexancourse.com.
