1. 1. NEWTON'S LAW OF UNIVERSAL GRAVITATION Group 5 1
2. 2. GROUP 5 Nguyen Khanh Linh Pham Thi Hang Phan Van Sang Do Thi Quynh An 2
3. 3. 01 03 02 04 TABLE OF CONTENTS Introduction Gravitational Constant Universal Law of Gravitation Gravitys use 3
4. 4. INTRODUCTION Who discovered gravitational law? 01 by Nguyen Khanh Linh 4
5. 5. ISSAC NEWTON (1642-1727) • One of the greatest scientists the world has known. • Some most important and famous discoveries and inventions o Gravity - Newton o Laws of Motion. o Calculus o Reflecting Telescope 5
6. 6. An apple fall from a tree • Why the apple fell straight down, rather than sideways or even upward.? • How did this explain why the moon orbited the earth? • What was the other force? 6
7. 7. Universal Law of Gravitation 02 7
8. 8. Newton’s universal law of gravitation • Every particle in the universe attracts every other particle with a force along a line joining them. • The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. 8
9. 9. Equation • F is the magnitude of gravitational force - N • m1 and m2 are the masses of the objects – kg • r is the distance between the centers of their masses - m • G is the gravitational constant, equal to 6,673. 10−11 𝑁. 𝑚2 𝑘𝑔2 9
10. 10. GRAVITY ACCELERATION 10
11. 11. GRAVITY ACCELERATION Newton’s universal law of gravitation With: m is the mass of the object M is the mass of Earth r is the distance to the center of Earth (earth radius) 11
12. 12. 03 Gravitational Constant 12
13. 13. Cavendish Experiments 13
14. 14. • Cavendish's measurements resulted in an experimentally determined value of 6,75. 10−11 𝑁. 𝑚2 𝑘𝑔2 • The currently accepted value is 6,67259. 10−11 𝑁. 𝑚2 𝑘𝑔2 Gravitational Constant Value => the force of gravitational attraction is only appreciable for objects with large mass. 14
15. 15. Calculate the Earth's mass and density 15
16. 16. Gravitys use 04 16
17. 17. Provides force to Satellites to revolve round the earth. 17
