The equation of motion for an object in free fall starting from rest is y$=1/2$gt$^2,$ where g is the acceleration due to gravity. This is the equation of a parabola, which has the general form y$=$ax$^2.$

Convert the curve into a straight line by plotting y versus t$^2.$ That is$,$ plot the square of the time on the abscissa$.$ Determine the slope of the line, and compute the experi$-$ mental value of g from the slope value.
