  • 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
    • any push or pull
    • can change an object’s position or direction of motion
  • 4. force
    • push 
    • pull 
    push pull
  • 5.  
  • 6. The greater the force on an object, the greater will be its change in its motion.
  • 7. friction
    • contact force that goes against the motion of an object
  • 8. Equal forces in opposite directions do not cause a change in motion. Tug of war
  • 9. gravity
    • non-contact force that pulls objects toward each other
    • the greater the mass  the greater the force of gravity
  • 10. weight
    • amount of gravity that pulls on an object
  • 11. magnetism
    • non-contact force that pulls on metals with iron in them
  • 12. Let's Review
  • 13. FORCE
    • any push or pull
  • 14. energy
    • It takes ________ to apply or exert a force.
  • 15.
    • A force can cause a _________ in an object’s position or motion.
    change
  • 16. GRAVITY
    • force that pulls objects toward each other
  • 17. FRICTION
    • contact force that goes against the motion of an object
  • 18. mass
    • the greater the _______  the greater the force of gravity
  • 19. IRON
    • Magnetism is a non-contact force that pulls on metals with ___________ in them.
