You will be designing and carrying out your own experiment to investigate the effect different forces have on an object’s motion. The experiment you design should test at least
one of the forces that affect motion that you have learned about in this unit. It should be
different than any of the activities you have already completed in this unit.
The experiment must follow the steps of the scientific method. The final product should
include the following information:
 research question
 list of materials
 hypothesis
 written procedures
 data table
 conclusion
