Ruben Diaz Jr Partner: Noel Shay Physics 1410 Lab Section 822 1/23/2017 Motion in Free Fall Lab # 2 Objective: To analyze the motion of an object in free fall. Through tracking an objects position in time while it is in free fall, we can derive its acceleration that is the direct result of the gravitational force exerted between the object and the earth. As the mass of the object itself is incredibly small compared to that of the earth, its force will be negligible, and the magnitude of acceleration will represent that of the earths gravitational force exerted on the object.
Introduction The experiment performed was a simple analysis of position versus time of an object in free fall. The object itself was a small, smooth, metal cube suspended from a piece of carbon transfer tape. The tape and weight, hence forth called the “system” was passed through a device known as a tape timer. The tape timer is set to make consistent marks on the tape at a rate of 1 mark for every .025s. By measuring the distance between the marks, we have the displacement of the object as it falls. By knowing that the time interval between marks is 1/40 th of a second, we have now effectively collected the position vs time of the object as it moves in free fall. We were told to ignore air resistance as for a smooth object, the value of air resistance will be very small and therefore negligible. By graphing the position versus time graph of the object, we can derive its velocity, and further derivation will provide us with the systems acceleration. Block Diagram of procedure
Procedure We began by obtaining a piece of carbon transfer tape, approximately 60cm in length. By using clear tape we created a loop at one end. From this loop we hung a small, square, metal weight. We then fed the top portion of the tape, through the plate of the tape timer.
