Första labben "avklarad"
Today we have finished our first lab, the second physics lab. It did not go very well in the beginning, because the miscount was unrealistically high. We had to redo the experiment over and over again to find what we had did wrong. In the end we found out that we had calculated the seconds for the falling weight wrong, and the experiment had to be done one last time to get results that sounded theoretically right.
Now we know that about 0.01 J/10 cm was lost when dropping a weight 1 m because of air resistance and friction.
