Yesterday you finished up activity one about wedges and levers. What did you discover about the placement of the fulcrum? Was the lever easier to use if the fulcrum was close to you or far away. Was the relationship of input force/distance to output force/distance direct or inverse?
Today we started activity two on the inclined plane and the pulley. What did you discover about inclined planes? What the inclined plane easier to use if it was long or short? What other factors might affect the use of the inclined plane?
