The proportionality constant G is defined as the universal gravitational constant and its value is G = 6.6732*10-11 N m 2 /kg 2. We know that, on the surface of the Earth: Solving for g gives: Now, knowing g and the radius of the Earth, the mass of the Earth can be calculated: (5-5) … ... PowerPoint Presentation Because of this, we say that gravity obeys an inverse square force law. . 17-6 Chapter 5. Although, of negligible importance in the interactions of elementary particles, gravity is of primary importance in the interactions of objects. 5-7 Gravity Near the Earth’s Surface; Geophysical Applications Now we can relate the gravitational constant to the local acceleration of gravity. a) Gravity is responsible for the atmospheric temperatures of the different bodies in our solar system. Planets and Gravity Since Jupiter is the largest planet, it has the most gravity. Questions If the planets are orbiting the sun , what force is keeping them in orbit? Let's explore more about Gravitation and find answers to these question. gravitation.ppt.ppt - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Gravitokinesis 6. Newton's Law of Universal Gravity • Gravity decreases with the inverse square of the distance, 1/r2. Graviton Manipulation 5. Unformatted text preview: Gravitation & Circular Motion 1 Centripetal Force Inwardly directed force which causes a body to turn; perpendicular to velocity.Centripetal force always arises from other forces, and is not a unique kind of force. . at the bottom right of the page.] Gravity varies as the product of the masses. Hence, the value of g decreases. Pluto has the least amount of gravity of all the planets THE HISTORY OF GRAVITY Sir Isaac Newton theorized the Law of Gravitation in 1687 UNIVERSAL LAW OF GRAVITATION Gravity is … Newton’s Law of Universal Gravitation Physics Mrs. Coyle Isaac Newton 1666, England (45 years after Kepler). The law of universal gravitation states that all objects are attracted to each other by gravity. Universal gravitation Gravity is a universal attraction between any two masses. These blanks are conveniently underlined and bolded on the teacher copy. Meaning of Gravitation. How Newton tied together the gravity observed on Earth and the motion of the Moon. . Newton’s Law of Universal Gravitation Nicolaus Copernicus- Polish astronomer who said that the Earth revolves around the sun, not the other way around! Equation of motion of freely falling bodies. • As the graph below shows, even though the force of gravity diminishes rapidly with distance, it never completely vanishes. Terms: Gravitation (or gravity), inverse-square law, solar constant. To appreciate the philosophical implication of Newton's calculation: all parts of the universe seem to obey the same laws of nature. . Test yourself: 1. The Law Of Universal Gravitation In The Late 1600s, An English PPT Presentation Summary :The Law of Universal Gravitation In the late 1600s, an English scientist and mathematician, Sir Isaac Newton, developed the law of universal gravitation. Universal Gravitation - The Apple, the Moon, and the Inverse Square Law ; Universal Gravitation - Gravity is More Than a Name Sources include gravity, friction, tension, electromagnetic, normal. 1. – Specifically, sun and earth • He concluded that the force of gravity decreases with the square of the distance, r. 2 1 r F ∝ Magnetism and gravity are noncontact forces. The student version of the PowerPoint contains multiple blanks that need to be filled in throughout the lesson. The gravitational interaction of antimatter with matter or antimatter has not been conclusively observed by physicists. Tied together the gravity observed on Earth and the Law of Universal gravity • gravity decreases with the inverse Law.
