there is this experiment i'm doing about Counteracting friction.
i've finished report, but i still wanna ask u guys so i can be sure that me report is good enough, u have to fill in the blanks it's about friction and lubricants ball bearings, incliniing surfaces etc, mind
so here goes:
question: which of the following strategies will make pulling a ____across a ____require the lest force?
(1st idea) , (2nd idea) , (3rd idea)
hypothesis: before conducting your experiment, predict what the outcome(s) of the test will be. a good hypothesis always includes a good reason
experimental design: before conducting your experiment, make a #erd list of all the steps you will use to conduct the experiment. do not forget to include a control test so comparisons can be made afterwards.
also write what your constants and variables will be
materials: write a point form list of the materials you will use in the experiment.
the report took me quite a while to complete *phew*
