This lab was designed to calculate the acceleration of gravity using the Smart Timers. The theory predicts that g = CACM/so. In the class, the “g” most time is considered to be 9. Mm/so. Materials Yellow plastic ball The Smart Timers Iron Bracket Clamp Target pad Photostat The yellow plastic ball is as subjects. Iron Bracket use to constant the height, and clamp use to stable the Smart Timers attached on the Iron Bracket. The Smart Timers is use to count the amount of time. Target pad is part of the Smart Timers, it use to when ball fall on it, it will back to Smart Timers to make it stop timing.

Photostat also the part of the Smart Timers, it use to back to Smart Timers the ball start drop, to make Smart Timers start timing. Procedure First check the height is CACM; place the Photostat with the bar and attached it to the lower clamp on the main bar-stand. Place the plug from the Photostat to the #1 spot on the smart timer. Tightened the clamp so that it is perpendicular to the main bar stand. And make sure place the “pad” on the floor directly below the Photostat, also do not step on the pad. Connect the plug from the pad to the spot on #2 spots on the smart timer.

Then turn on the smart timers, now press #1 “button” to ‘time”. Now press the #2 button 3 times until it says “2 gates”. After below the step, push the “3 Button” twice until a “star” shows up and take the “yellow” plastic ball and position it near the Photostat. After pressing “3” start/stop button twice until a “star” appears on the screen, release the yellow plastic ball and measure the time it takes to fall. Do this 10 times and take an Data The following chart details the ten times trials of the experiment and includes an average of the ten times trials.

The data also show the average value of time and “g”. (Throw out an extremely large or small value) The result have an anomalies, it’s much bigger than the prediction that g CACM/so. It has a considerable error with prediction. The new hypothesis need to make sure the ball is drop from the same height, use hands to begin the drops will be have too much error, choose a heavier ball, to reduce the impact of air resistance. Shorten the connect line both between the Photostat and smart timers, and pad and smart timers. Error Analysis The result has a considerable error with prediction.

The most likely cause is air resistance and height not content. Use hand to start drop the ball is hard to constant the height, here will have some error, and plastic ball may too light, it is susceptible to get effect by the air resistance. Also the smart line connect line data transmission time will be effect the result, but this time is almost negligible, and under the present conditions, it is no way to improve that much. The data result with prediction has about 47. 83% errors. Conclusion The experiment is to calculate the acceleration of gravity using the Smart Timers.

In the conclusion, this lab seems to didn’t have generated strong support for the theories and hypothesis that g = CACM/so. The error make the result with forecast has a large gap. Air resistance and height is just relatively constant are the most reasons. Set a constant height will be better than use hands to drops the ball. Change the yellow plastic ball to an iron ball or other heavier ball will be much decreases the effect from air resistance. And have more tests will be better to confirm the results, if each personal do the ten times, then compare the each result, more tests is help to reduce errors.
