Purpose
The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations.

Results/Data

Part 1: The Motion Sensor

Motion Sensor’s Measurement of Distance on ‘Short Range’ 1 m
Closest Measurable Distance on ‘Short Range’ 0.12 m
Closest Measurable Distance on ‘Long Range’ 0.12 m
Distance from Center Line for First Detection of Block on ‘Short Range’ 0.05 m
Distance from Center Line for First Detection of Block on ‘Long Range’ 0.055m

Equally, a reading of 1.00m was obtained when measured on the short range setting (Table 1). The percentage deviation was negligible, at 0 %. A correction factor was applied while calculating the subsequent 1-m distances that were used to compute the range of the motion sensor. This ruled out any possibilities of discrepancies, suggesting that the experiment was conducted with a high degree of precision and accuracy.
With the Motion Sensor set on ‘Short Range’, it got as close as 0.12 m to a target before incorrect readings are shown. This distance was determined from the point where the motion sensor moved towards the distance where no readings could be obtained after which, it reversed to the 1-meter distance where the readings were picked up by the sensor. This trend is illustrated in Figure 2 where the graph bottoms and levels out on the parabola before rising up once more.
When the Motion Sensor was set to long range, the closeness to the target was no different from the ‘short range” setting, that is, 0.12 m. Afterwards, the readings became

    To get a result as close to the ideal model as possible, the angle from the equilibrium point to the maxima should be significant small. So small that the amplitude, which has the shape of an arc, could be assumed to be a straight line. In that case, the oscillations could be treated as simple harmonic motion and the calculations would be able to give a realistic result. The period is obviously affected by the angle as well, since it takes longer time to complete one period if the angle is greater. As seen in table 1, our raw data has a fairly big spread even though the length of the string is constant, which is a result of different angles.…

    The p-value, the probability of observing the same results or more extreme results, was then computed. The p-value for this data was p= 0.614 compared to the standard significance level of 0.05showing we cannot reject the null hypothesis (Figure 3). In other words, if we were to see this population again, if the two samples were the same is 61.4%. This suggests that there is no significant evidence showing that a longer drive will lead to a better…

    Conclusion The results of our experiment were satisfactory. Only one of the percent errors was slightly outside of the acceptable range. In the future, it would be preferable to repeat each measurement at least three times to get a more precise number. If we had more time in the laboratory to do the experiment, it would be more feasible to get a percent error closer to…

    The signal strength and the base line highly depend on the connection between the electrodes and the skin. First we used electrodes made for TENS machine with resistance about 100 ohms which worked fine in a relatively noiseless environment but it turned out to be unproductive during the lab, due to the high level of electromagnetic noises. Finally, we used proper ECG electrodes with resistance of around 10 ohms. These high quality electrodes functioned very well, but unfortunately after a given time period we had to dispose them as they became useless. Possibly, because of the gel inside dried out and didn’t conduct anymore.…

    Discussion From this experiment, it can be determined that the value of the coefficient of friction between the wire and the belt is 0.2782 (which is dimensionless). In addition, T1 becomes smaller (so the belt tension ratio becomes greater) when the angle of contact is increased, which can be explained by considering equation 2, as T2 cannot change for a given stationary mass. Comparing the experimental results to the theoretical predictions (made from the calculated value of μ, there is a relatively good agreement, especially when neglecting the πc result. The slightly higher gradient of the experimental results is likely due to an error (systematic) in the calibration of the load cell, causing it to become more inaccurate at higher tensions.…

    There is only a 29-unit difference between the minimum and maximum values. The next increase in size of 2cm x 2cm is even more precise with a small difference of 8-units between the values of 353, 357 and 361. The final cube size of 3cm x 3cm, had a large difference from the minimum and maximum values of 234-units. During the experiment it was observed that a small amount of the 3cm x 3cm cube was not completely submerged by the solution. This was a human mistake which is possibly the reason for such variation in the trials and the absence of any pattern throughout the data.…

    Therefore we can say that: Tsinθ/Tcosθ= (-ma)/mg tanθ= (-a)/g In our investigation we are going to keep the angle θ of the pendulum very small therefore we can say that the length L is going to be approximately the same for T. Also tanθ will approximately equal to sinθ. sinθ=(-a)/g x/l= (-a)/g ∴a=(-x)/l g Using the laws of circular motion we can calculate the time period using the values for a we found above. w=2πf a=-(〖w)〗^2 x Where w is the angular speed and f is the frequency. Using the equation above for a we can set it equal to the one we found previously to find T using f from angular speed. (-x)/g=-(〖2πf)〗^2 x g/l=(〖2πf)〗^2 √(g/l)=2πf f=√(g/l)/2πf T=2π√(l/g) We can also solve for g to find the acceleration due to gravity from our result by rearranging the equation.…

    The optimum stretching of TBC hydrogel was obtained at a draw ratio of 1.2 without any initiation of fracture in TBC. Stretching higher than 1.2 draw ratio showed initiation of fracture in the hydrogel for nearly all cases. On the other hand, lower cross-head speed was found to be the best for controlled stretching up to the maximum draw ratio. The cross-head speed was set to 0.03 mm/min based on the preliminary experiments. Lower cross-head speed gives sufficient time for maximum rearrangement and reduces the stress on nanofibrils.…

    The graphs above demonstrate that there is a value, but theoretically this value should be zero. As demonstrated in Table 1, every trial lost momentum. As the formula for momentum is and the mass remained constant, the velocity must be the responsible factor. Additionally, the only the magnitude of is necessary to observe adherence to the conservation law. The conservation law states that should be equal to zero, and as this wasn’t observed in any trial, it can be said that the conservation law was ineffective in this system.…
