The dependent variable is the position (y-axis) and the independent variable is the time (x-axis). This is the measured position of a rock as it falls from the top of a very high cliff and obeys the equations y = 1/2gt2. Make sure you label the plot properly. Right click on a data point in the graph and add a “Trend line.” Select a polynomial of order 2. This is a parabolic equation and describes an object falling under constant acceleration. Also check the box that says ‘Display equation on the graph.” Since the acceleration of gravity is 2 times the coefficient of the x2 term, what do you find for the acceleration of gravity. I have the graph, I just need help with the part below the table.
