Theory: Using the data collected, we can graph all ten distance versus time readings on a single graph. Calculate the slope of the line of closest approximation. Record this value of the constant C in the equation s(t)=Ct 2 . Then use calculus to show acceleration is equal to 2C. Local gravitational acceleration constant equal 2C Use the constant acceleration equation y(t)-y =(1/2)gt 2 +v t to calculate the acceleration Calculate the value of g for each of time trials g avg =g= Calculate the root square average (the standard deviation) g RMS = g- g12 + g- + g22 … .+ g- gN2N g=g avr ± g RMS Apparatus: 1 36” metal rod, 1 right angle clamp, 1 24” metal rod, 1 drop box, 1 control box, 1 wire cable, 1...
