# gravity and gravitation ppt

... PowerPoint Presentation Sources include gravity, friction, tension, electromagnetic, normal. Khan Academy is a 501(c)(3) nonprofit organization. 1. Close suggestions. - Gravity in Space - Law of Universal Gravitation - The Power of Gravity - How Gravity Affects the Tides - Objects in Circular Orbit - Our Bodies in Microgravity. Gravity is a "central" force (center-to-center for spherical bodies). Gyrokinesis 9. These blanks are conveniently underlined and bolded on the teacher copy. Chapter 5. When we move from the poles to the equator. Questions If the planets are orbiting the sun , what force is keeping them in orbit? Circular Motion; Gravitation Big Idea: Circular Motion is Accelerated Motion There are 3 ways to accelerate: Speeding Up (acceleration supports velocity) Slowing Down (acceleration opposes velocity) Changing Direction (acceleration is perpendicular to velocity) a v a v v a Universal Gravitation (Why are we attracted to that big bright object in the sky) Newton’s Big Idea • Newton developed the idea that two bodies exertf hth ditt a force on each other over a distance. The gravitational interaction of antimatter with matter or antimatter has not been conclusively observed by physicists. Meaning of Gravitation. Universal Gravitation - The Apple, the Moon, and the Inverse Square Law ; Universal Gravitation - Gravity is More Than a Name Quantum Gravity; Introduction to Gravitation. 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) and Dactyl orbiting Ida . . If the page doesn't load quickly click on Impatient? At the 20th century, Newton’s Law of Universal Gravitation was accepted by all. Begin with an introductory article with questions (answer key provided) and then follow up with a PPT and student notes. Strong Nuclear Force Increasing Strength Kinds of Forces + proton electron Strong Force binds together protons & neutrons in atomic nuclei n Weak Force: Decay of the Neutron + proton electron GRAVITATION GRAVITY keeps the moon orbiting Earth . He said that the force of gravity or gravitational force exists between all bodies. The PowerPoint is an introduction to gravity, weight, projectile motion and centripetal force. Scribd is the world's largest social reading and publishing site. Universal Gravitation Newton recognized that the force of gravity between any two objects with mass is directly proportional to the product of the masses, and inversely proportional to the square of the distance separating the masses. The student version of the PowerPoint contains multiple blanks that need to be filled in throughout the lesson. Gravitational Field Manipulation 3. Gravitation Notes: • Most of the material in this chapter is taken from Young and Freedman, Chap. Gravity Control 7. Why? • As the graph below shows, even though the force of gravity diminishes rapidly with distance, it never completely vanishes. a) Gravity is responsible for the atmospheric temperatures of the different bodies in our solar system. Sir Isaac Newton - the law of universal gravitation [This expired link is available through the Wayback Machine Internet Archive. Equation of motion of freely falling bodies. Forces of gravity are directed along the line joining the interacting particles and are, therefore, called central forces, which is conservative. … Gravity varies as the inverse square of the center distance. Test yourself: 1. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Gravity is a force at a distance (through occupied or empty space). . This resource was created to introduce the topic of gravity as a force. According to Newton’s gravitational force is caused by matter. Newton’s Law of Universal Gravitation Nicolaus Copernicus- Polish astronomer who said that the Earth revolves around the sun, not the other way around! The scientist discovered the existence of this force was Isaac Newton. 13. Difference Between Gravitation and Gravity Even though both the terms sound alike but there is a difference between gravitation and gravity, gravitation is the force occurring between two bodies whereas gravity is the force occurring between the earth and a body. How Newton tied together the gravity observed on Earth and the motion of the Moon. 5.1 Newton’s Law of Gravitation We have already studied the effects of gravity through the consideration of the gravitational acceleration on earth g and the … Planets and Gravity Since Jupiter is the largest planet, it has the most gravity. When the bodies are falling under influence of gravity, they experience acceleration g i.e., 9.8 ms-2.However, when these are going up against gravity, they move with retardation of 9.8 ms-2.All the equations of motion already read by us are valid for freely falling body with the difference that a is replaced by g.
