  1. CH. 12 LESSON 2 HOW DOES FORCE AFFECT MOTION?
  2. Activity-Roll On Hypothesis : I predict that the truck will go further with or without rocks. Without rocks With rocks Distance (cm) truck
  3. force <ul><li>any push or pull </li></ul><ul><li>can change an object’s position or direction of motion </li></ul>
  4. force <ul><li>push  </li></ul><ul><li>pull  </li></ul>push pull
  5.  
  6. The greater the force on an object, the greater will be its change in its motion.
  7. friction <ul><li>contact force that goes against the motion of an object </li></ul>
  8. Equal forces in opposite directions do not cause a change in motion. Tug of war
  9. gravity <ul><li>non-contact force that pulls objects toward each other </li></ul><ul><li>the greater the mass  the greater the force of gravity </li></ul>
  10. weight <ul><li>amount of gravity that pulls on an object </li></ul>
  11. magnetism <ul><li>non-contact force that pulls on metals with iron in them </li></ul>
  12. Let's Review
  13. FORCE <ul><li>any push or pull </li></ul>
  14. energy <ul><li>It takes ________ to apply or exert a force. </li></ul>
  15. <ul><li>A force can cause a _________ in an object’s position or motion. </li></ul>change
  16. GRAVITY <ul><li>force that pulls objects toward each other </li></ul>
  17. FRICTION <ul><li>contact force that goes against the motion of an object </li></ul>
  18. mass <ul><li>the greater the _______  the greater the force of gravity </li></ul>
  19. IRON <ul><li>Magnetism is a non-contact force that pulls on metals with ___________ in them. </li></ul>
