Measurement of Free-Fall Acceleration

Measurement of Free-F in all Acceleration Introduction         Galileo Galilei (1564-1642), the objet dart first accredited with the correct notion of free-fall with unvarying acceleration, state that if one were to remove entirely the resistance of the medium, all materials would flow with equal speed. Today, this statement holds true for all objects in free-fall surface the Earths surface. The purpose of this experiment is to verify Galileos assertion that acceleration is constant. In addition, the magnitude of acceleration lead be calculated. Theory         By definition, acceleration is the rate of throw of velocity with respect to period. instant(prenominal) acceleration is the derivative of velocity with respect to time. a(t) = dv / dt. Average acceleration is the depart 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 det ermined 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 logical argument 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 deuce vertical conducting fits, a thin strip of written theme 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 electric ! instant to the wires approximately 60 times a second. Every time a pulse is transmitted, two master(prenominal) sparks flow through the system. bingle spark passes from one wire to the metal girdle close to the tilt. The second spark causes a small burn in the paper, marking the location of the weight at that instant. Procedure offer on the...
