Abdul KhalidPHYS 1410L- 807Andriy Danylov9/20/2016Brett Bamford, Jared HathwayFree Fall MotionObjective(s): The objective was to measure the rate at which velocity changes with time,and use the data to calculate the acceleration due to gravity pertaining to the motion ofa free falling body under the influence of gravity.Introduction:Theory: The experiment is conducted on the basis of the theory that when a body falls freely within the earth’s atmosphere, as long as the fall distance is less than the radius
of the earth, then the acceleration of the object in free fall will be equal to that of the acceleration due to gravity and remain constant. Thus, the acceleration due to gravity for the free falling object in this experiment must remain constant until reaching the ground.Equations:1.a= (VV0)tThe equation can be used to calculate time as well by rearranging and obtaining: t= (VV0)a, or find V by multiplying “a” to both sides, and adding velocity initial to both sides to obtain V= Vo + at.2.V=xt3.V=V0+V24.Derivative: X= V0t + ½(a)(t)^2The v would equal final velocity, while v0 would be initial velocity, a would be acceleration, t would be time, while x would be displacement. Apparatus & ProcedureA.Equipment used: A 60cm roll of tape, a tape timer unit, a 200 gram mass, a table clamp, vernier calipers, table, and a meter stick.B.Block Diagram:Measure Tape to 60cm
Hook mass to tape stripSlide the strip through time unitActivate unit, let strip goC.Procedure: First a strip of tape was measured against a meter stick, and cut at the 60 cm mark so that the strip is 60 cm long. Then a 200 gram mass was attached to the piece of tape by forcing the hook of the mass through one end of the tape. The other end of the tape was slid through the timer unit and held up byhand, whilst the timer unit was attached to the table using a table clamp. The timer was set to 40 Hz, and as soon as it was switched on, the piece of tape was let go so that the weight of the mass pulls the tape and both free fall towards the floor. As the tape fell through the timer, the timer made dots throughout the tape strip. The dots served as demarcation throughout the tape strip, with the distance
