  1. SPI 0807.12.5 to 12.6 Gravity PRESS THE RIGHT-ARROW BUTTON ON YOUR KEYBOARD TO ADVANCE THROUGH THE SLIDES!  Notes Newton discovered the law of universal gravitation. Einstein theorized that mass warps/bends/curves space and this warping explains the force we call gravity Gravity is a "pulling" force that causes every particle of matter to be attracted to every other particle of matter The force of gravity causes our planet to rotate (spin), and it also makes the planets revolve (orbit) around the sun 1

  2. SPI 0807.12.5 to 12.6 Gravity Notes Earth’s Rotation and Revolution Gravitycauses our planet to rotate on its own axis Gravity keeps our planet (and all the other planets) from “flying off” into space as it revolves (orbits) around the sun (Do demonstration of rotation vs. revolution) 2

  3. SPI 0807.12.5 to 12.6 Gravity Gravity and the Motion of the Moon Notes • Gravity keeps the moon from “flying off” as it revolves (orbits) the Earth • (See Holt Online Ch15: Sect 4 Visual Concepts) • VC about gravity and orbits 3

  4. SPI 0807.12.5 to 12.6 Gravity Review 1) What is one way gravity helped form our solar system and planets? A) By pulling matter together B) By pushing matter apart 2) What is another way gravity helped form our solar system and planets? A) By making objects revolve and rotate B) By making objects move in straight lines 3) Contrast revolution and rotation A) Revolve=moving around another object, Rotate=spinning on an axis B) Revolving is faster than rotation and has more gravity 4
