HW for Thursday

homework to bring Thursday 

Hey everybody! 

You've collected some data today.  For homework, take a look at the data.  What variable(s) seem to affect the time of the pendulum?  What affects it a lot?  A little?  Nothing at all?  Can you tell?

Pick the set(s) of data that matter most and graph them.  Time (the dependent variable) will be on the vertical (y) axis.  Mass, initial height/angle, or length will be on the horizontal (x) axis - these are all independent variables.  In general, the independent variable goes on the x-axis and the dependent variable is on the y-axis.

Make one or more graphs and see if any relationship pops out at you.

Either hand-draw the graphs on graph paper or use a computer (Excel or some online graphing program).  Bring the print-out of the graph(s) or the handwritten copies to class.
