Measuring the velocity of various objects in freefall

Purpose: The purpose of this experiment was to measure the velocity of various objects in freefall. Upon completion of this lab one will be able to calculate the values for acceleration and the effect of air resistance. Apparatus: 2m clear plastic tube Acculab sonic ranger (speed of sound = 343 m/s period = 0.03 seconds) SensorNet software Macintosh computer with system 6.07 or later Blank 3.5 HD Macintosh formatted disk Electronic mass scale, calipers Various objects to drop Procedure For …

…approaches 'g.' We also concluded that the downward acceleration is not related to air resistance. However we did find a relationship between velocity and the force of resistance. As the velocity of the object increases, the force of resistance decreases. We also found that the mass of an object has no effect on the downward acceleration of the object in freefall. From this experiment one discovers the relationships between different properties of an object.
