LEARNING OBJECTIVES:

  • Understand that an inclined plane supports an object by pushing up on it.
  • Discover that inclined planes help make lifting an object easier by combining their supportive force with the lifting force applied by whoever is pushing the object.
  • Relate the length of the plane to the reduction in required force.
  • Be aware of disadvantages of inclined planes.
  • Discover that friction causes work (energy) to be wasted when sliding objects.
VOCABULARY:
  • friction, inclined plane, work
