Physics Journal #2

This picture, for demonstative purposes only, represents a rather fortunate accident that occured to me on Saturday. While i was rushing to pack up my guitars and amp to head to a friend's house to jam i spun suddenly when i heard the house phone ring, swinging the guitar on my back and accidently sweeping both my cell phone and my cup of Mitsuya Cider off the table. As i stood back, (as i look back on it, surprisingly calm at this potentially depressing incident) i did not see possible destruction of my phone, but the two objects falling at the same speed (ignoring air resistance, -9.8 m/s) and hitting the ground at (almost) exactly the same time. This is because everything on Earth is equally affected by the presence of gravity during free fall, which causes all objects, no matter their size or weight, to accelerate at -9.8 m/s, assuming air resistance is not a factor. Although my cell phone was clearly lighter than the cup full of Mitsuya Cider, gravity caused them to accelerate at the same rate, so they both had the same velocity throughout the entire fall. This little incident helped me to grasp the concept of free falling, and helped reinforce the principal that all objects, no matter their weight, fall at the same rate (in a vacuum) because of gravity.
