- 1. Newton’s Law of Universal Gravitation G = 6.67E-11 N. m2/kg2 Fg = GMm/r2
- 2. All Objects in the Universe pull on all other objects. • The distance (r) must be center to center. •
- 3. Center to Center, even on earth.
- 4. From the earth, and between the objects themselves. Pull from man to earth. Pull from center of earth to man.
- 5. How does the Solar System Work?
- 6. Here is the proof:
- 7. Science Fiction? • "The Force is what gives a Jedi his power. It's an energy field created by all living things. It surrounds us and penetrates us. It binds the galaxy together.“ • https://www.youtube.com/watch?v=MTY1Kje0yL g • Truth: Gravity is an energy field; It surrounds us and binds the OBJECTS in the UNIVERSE together. It is a force. Just not THE force. And it is with us.
- 8. From Kepler to Newton:
- 9. Example Problems: Finding g on any planet. • g = Gm/r2 • What is the acceleration of gravity on Earth? • G = 6.67e-11 • mearth = 5.98e24 kg • earth radius = 6400e3m • g = 6.67e-11 * 5.98e24/(6400e3)2 • g = 9.8 m/s2
- 10. Way to find the mass of the earth. • g = 9.8 m/s2 was already known, Newton could calculate G = 6.67e-11, and the radius of the earth was already known. So with those values scientists were able to calculate the mass of the earth.
- 11. Find the mass of Mars: • g = 3.5 m/s2 on the surface. • radius of Mars = 3390 km or 3390e3 m G = 6.67e-11 3.5 = 6.67e-11 * m/(3390e3)2 Solve for m (3.5 * 3390e3)2/6.67e-11 = m
