Measurement of Free-Fall Acceleration

Measurement of Free-F in all Acceleration Introduction         Galileo Galilei (1564-1642), the human beings first accredited with the correct notion of free-fall with unvarying quickening, utter that if one were to remove entirely the resistance of the medium, all materials would accrue with equal speed. Today, this statement holds true for all objects in free-fall skilful the Earths surface. The purpose of this experiment is to verify Galileos assertion that quickening is constant. In addition, the magnitude of acceleration volition be calculated. Theory         By definition, acceleration is the rate of throw of velocity with respect to quantify. instant(prenominal) acceleration is the derivative of velocity with respect to time. a(t) = dv / dt. Average acceleration is the flip in velocity during a time interval, Dt, divided by the length of that interval, aave = Dv / Dt. In this experiment, middling acceleration of gravity will be determined by measuring the change in location of a falling object at on a regular basis time intervals. With this, average velocities for these intervals will be calculated. A chart of the average velocities versus time should give a straight bourne whose hawk is the acceleration of gravity (g). Apparatus         To determine the acceleration of gravity the Behr weapon will be used.

The device consists of both vertical conducting fits, a thin strip of written penning held amid them, and a metal-girdled fish designed to fall between the wires along the length of the paper strip. A spark timer transmits a high potential drop elect! ric momentum to the wires approximately 60 times a second. Every time a pulse is transmitted, two master(prenominal) sparks flow through the system. maven spark passes from one wire to the metal girdle almost the tilt. The second spark causes a small burn in the paper, marking the location of the weight at that instant. Procedure puzzle out on the...
