Then we found the radii of the objects been used M ( steel ) M ( hanger ) Height ( h ) We placed a given mass on the hanger, and then released it and let the hanger fall under gravity. We measure the time it took to hit the ground. For the given mass we took six measurements, and found the average time. We then repeated the experiment for 5 different masses mass used ( g ) m ( total ) (g) t 1 (s) t 2 ( s ) t 3 ( s ) t 4 ( s ) t 5 ( s ) t 6 ( s ) t` ( s ) Acceleration " a " with 0 mass used Acceleration " a " with 5g mass used Acceleration " a " with 10g mass used = 2 * h t ^ 2 = 1.3 cm / s^2 = 2 * h t ^ 2 = 1.53 cm / s^21....
