Formal Lab Report Experiment 3: Determining the Acceleration of Gravity Performed by: A. Morrisey Partner: K. Lochkajian Lab Preformed: November 6, 2009 Report Submitted: December 1, 2009 Purpose The purpose of this experiment is to determine the acceleration of gravity using a linear air track. Apparatus 1. Linear air track (see Fig. 2) 2. Linear air track rider w/ an attached metal “flag” (see Fig. 2) 3. one photogate 4. one accesory photogate 5. ruler 6. vernier caliper 7. ten risers See Figure 2 for a schematic diagram of the arrangement and use of the aparatus. Theory According to the kinematic equation of motion, if an object is subject to constant acceleration

Unformatted text preview: a , it will travel a distance, S , over a time interval of t , where v0 is the initial velocity, which in this case is zero because the object is starting from rest. This gives us the following equation. = + S v0t 12at2 ‘ Fig. 1 If an object starts from rest on an inclined, frictionless plane on an angle θ , then the only force acting on the objecting causing it to accelerate down the ramp is the accelaration due to gravity. Because the object is on a inclined plane, the acceleration is identified as such, = a gsinθ . The equation now becomes: = + ( ) S v0t 12 gsinθ t2 or = +( ) S v0t gsinθ t22...
