The acceleration due to gravity from the acceleration of the ramp is 7.5m/s2. 7 trials were done to get the correct amount of error. The angle of 9° was found by dividing the 10cm of height of the ramp by the base of 105.5cm of the ramp. Sin θ = 10cm/105.5cm = .94 = 9°. The total acceleration of the cart was 1.172m/s2 because it was divided the total distance by the total time and multiplied by two a = 2(105.5cm/1.8s) = 117.2cm. 117.2 were converted into meters 1.172m/s2. Precision will matter because the faster it takes the cart to roll down the ramp, the higher the error percentage will be. The slope of the v-t graph is constant because the rate of acceleration is not changing and going in the velocity. For the p-t graph the slope is increasing while rolling down the ramp. Delta d was the hypotenuse of the ramp (105.5cm). It took the cart 1.8s to travel 105.5cm down the ramp. The percentage error should be a small amount so it would not affect the result of acceleration due to gravity. Errors…show more content…
Error can be fixed by having an average degree angle and error percentage lower than 8%. Error can be calculated by dividing a second by the total time (1s/1.8) = 5%. The skills learned or practiced in this lab were to find g (9.8m/s2), use the Pythagorean Theorem, (a2 + b2 = c2 and solve for acceleration (delta d/
