On the ruler, leading to an extra time delay. Is partly caused by delay in stopping the stop watch and partly caused by the ball bouncing Value of ‘g’ is 9.80 m/s2 with an error of 0.01 m/s2. The value of ‘g’ obtained is 8.943 m/s2 with an error of 0.794 m/s2, whereas the accepted The value of ‘g’ is calculated using the equation d = ½ gt 2.
Made to fall from various height of 0.5m, 0.75m, 1m and 1.5 m and time taken for the object
