Question
A body falls freely downward from a certain height. Show graphically the relation between the distance fallen and square of time. How will you determine 'g' from the graph?

Answer

For a freely falling body, the displacement is directly proportional to the square of time. By knowing the slope of displacement Vs. square of time graph, we can find the acceleration due to gravity.
