Purpose: This lab is meant to prove the acceleration of a falling object without any external forces besides gravity is 9.8m/s^2.
The way we prove this is by using an a free fall body that is connected to an electromagnet. When the free fall body is released it will fall along side a strip of carbon paper and leave little marks indicating a certain distance it fell during a certain time.
Once the spark generator has fallen the 1.5m distance, we take the piece of tape and measure the distances between the dots on the paper.
The dots were hard to see so we darkened them with a pen and wrote the distances measured from zero. We are only meant to measure 11 dots because any more then that would be a little too much.
Once all of the distances were gathered we had to chart them on Excel along with a column for time, the change in distance, mid interval time and mid interval speed.
Then once that is gathered we were meant to create a graph of the mid-int speed vs the mid int time. By graphing this data we were able to gather our acceleration in cm/s^2.
After gathering our own acceleration, the whole class put all of there accelerations in a chart in order to figure out the deviation between us.
However, since our g value turned out to be really high a majority of the class took it out of their calculation. With our g value being so high it increased the average deviation significantly.
