Good evening this is Janell Stealson with channel eight news reporting live. Today we are at Manheim Township High School in Mr. Manning's seventh period physics class. Today Mr. Manning's class went over both labs the first one was the Manning Made Pile Driver Lab. In this lab the students were expected to find if the average friction force would increase, decrease, or remain unchanged. In this lab the physics students had to put a nail into a block of wood and measure the height at which the driving cylinder fell. They had to repeat this six times at three diffrent heights. So the team and I took a crack at this lab. Brian Roach came along today and we completed this lab together. Brian Roach and I first made our prediction that the average resisting force would increase. Next we began by dropping the driving cylinder from a height of .513 meters. We did this twice. Then we dropped the driving cylinder from a height of 1.105 meters. We also did this twice. After this we dropped the driving cylinder from a height of 1.695 meters we did third twice also. After Brian Roach and I completed the experiment and recorded our findings. We had to answer some questions on the back of the lab worksheet. The first question was, did the resisting force increase, decrease, or remain the same as the driving metal cylinder was dropped from a higher position? We looked back at our data and found that the resisting force remained the same as the driving cylinder was dropped from a higher position. Then we answered question two that read, if the driver were more massive, would the resisting force remain the same? (If you are unsure, take a one-kilogram mass and sit it on top of the driver. Then perform the above experiment again. Our answer to this question was, the resisting force would remain the same because the mass does not affect the resisting force. Question number three, if the experiment was performed on Mars, would the displacement of the nail be more, less, or equal to the experiment performed on Earth? Brian Roach and I answered, that the displacement would be less because there is less gravity ob Mars than on Earth. Which would make the displacement less. The last question was, if the mass of the driver doubles, find the new displacement of the nail if the height and resisting force remain unchanged. Well Brian Roach and I had to get back to the station but we answered the question, as the new displacement would double because of the mass of the driver because it putts the nail farther into the block of wood.
