Isaac newton presentation

  1. 1. Isaac Newton and Gravity An Invisible Force
  2. 2. Gravity • Every object pulls on every other object with an invisible force called gravity. • There is gravity between you and your toy car, but you won’t notice it because it is so weak.
  3. 3. Gravity • You can, however, feel the pull between you and the Earth. • That’s because the force of gravity depends on an object’s mass, and the Earth has a lot of mass.
  4. 4. Gravity• The earth has so much mass that it pulls everything downward toward its center including the oceans and air. Even the moon stays above the Earth because of gravity.
  5. 5. Isaac Newton • Over 300 years ago a scientist named Isaac Newton explained this invisible force of gravity.
  6. 6. Newton’s Discovery • Newton was sitting in his garden when he saw an apple fall from a tree. • He decided that some force must be pulling the apple to the ground. • He called it gravity.
  7. 7. Test Your Knowledge • You already know a lot about gravity. • That’s because it’s at work all the time. • Let’s test your knowledge.

  17. 17. Fighting Against GravityWe can overcome but we have to use force gravity, to do it.
  18. 18. More About Gravity • Hang On! • There’s more to Come!
