The object of the experiment is to determine whether or not objects fall freely at the same rate and speed. Measure and calculate the time in which it takes random objects to hit the ground from a certain height and determine if the objects have the same rate of motion or not. Materials: 1. Meter Stick 2. Stopwatch 3. Wallet 4. Quarter 5. Tape 6. Hot sauce packet from Chinese food delivery 7. Container of wipes 8. Football 9. Golf ball 10. Pen 11. Nail 12. Piece of paper Procedure: 1 . Gather your materials. 2.
Find a location suitable for dropping your object. 3. Set a vertical distance from which you will drop your random objects. Use the same distance for all objects. 4. Drop each object from the top of your distance and have a partner time with a stop watch the amount of time the objects take to fall. The piece of paper should be the last to be timed. 5. Record ten trials for each object. Data & Observations: There are a variety of factors that affected the outcome of my data. Some were: Failing to release the object at the perfect time. Not starting or stopping the stop watch at the perfect time.
I noticed that it took all the objects about the same time to reach the floor. If some of the objects were subject to a bit of air resistance, it caused the object to fall a bit slower. I observed this with the hot sauce packet, the pen, and the wallet because it was a bit thin. This caused a bit of a problem and increased my percent error. When a piece of paper was dropped, detected a difference in my results. The paper fell unnaturally and didn’t have the same direct path as the other objects did but rather an odd one. The reason for this is air resistance.
Air resistance is a Orca that acts in the opposite direction to an object moving through the air. This force caused a disturbance in my calculations. When the paper was released with the thin side facing down, it fell quickly but then took a bizarre path. When it was dropped with the flat side up, the paper fell sluggishly. In the operations I conducted, I dropped it with the thin side down. I learned that the force of gravity works equally among all objects falling freely from rest. If one were to drop all of the objects at the same time from the same height, all the objects would hit the ground at the same time.
Unless, however, if there is an opposing force acting on it such as air resistance, like we observed on the piece of loose leaf paper. If were to repeat this lab in the future I would maybe use a longer distance to calculate how long an object takes to reach the ground. Also, instead of dropping it from my hand I would start it from rest maybe at a high table and lightly push it off and start my timer as soon as the objects left the ledge. The procedure done that way may provide worthier figures and possibly make the lab experiment computations a bit more precise.
