Purpose:
To determine the efficiency of the inclined plane.
Objective:
The student will use the data from lesson one to determine the efficiency of the inclined plane.
Materials:
____
Data from lesson one.
Procedure:
Efficiency = resistance force x resistance distance/ effort force x effort distance x 100%
Observation:
Efficiency = 64g x 10cm/22gx30cm x 100%
Conclusion:
____
The efficiency for this simple machine is -97%
