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
Table 1:
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

As before the colour excess for M39 is 0.01 resulting Av = 3× 0.01 = 0.03. The apparent magnitude mv is 8.8 and the absolute magnitude Mv is +0.70. The uncertainty in the main sequence recorded the maximum value 15.00 and minimum value 9.00 in Y-axis which gives 15.00-9.00 = ± 6.00. Now we need to plug all known values in equation 1 to calculate distance in parsec as below: d = 10 (8.8-0.70+5-0.03) /5…

I believe that the author try to establish the validity and reliability of the measurements by adding some of the control variables to control the measurements. However, I still believe that the measurements are unreliable, because of the sampling error. 4) Are any hypotheses stated? Are these hypotheses justified in terms of theory or previous…

Lab 2 Summary In this lab, the purpose was to understand how to use a DMM to measure different things like resistances, current, and voltages as well as how to successfully comprehend the electrostatic relationship between various objects. In the first part of our lab we learned how to use a Digital Multimeter by using a simulator to draw diagrams of circuits. This helped give us a basic understanding that when dealing with a circuit and tools like a DMM, you have to connect wires to certain places and make sure the positive is touching the positive side. In the second portion of the experiment, we learned how to use the equipment that will be used for the other labs.…

Eggs-traordinary Physics \$875.00 This physics-focused camp turns the study of motion and mass into hands-on projects and team-building challenges! Students spin, toss, race and design throughout this camp to learn about ideas of motion, such as velocity, speed and how gravity plays a role in each of these activities. These egg activities are not only engaging, but provide valuable reinforcement of physics concepts, which often can be difficult to understand without active demonstrations. Teamwork is encouraged as students work to reach success in this egg-citing camp that will turn any student into a physicist!…

Hipparchus was an original mathematical genius; his distinctive, discoveries were pertinent in early history of science and math. Greek astronomer Hipparchus discovered trigonometry which derives from the Greek words trigonon “triangle” and metron “to measure”. Even though there were signs that the Egyptians used different ratio signs there was never proof they thought in terms of angles. Hipparchus spent a lifetime observing astronomy, which led to most of his discoveries. In order to make the mathematical computations required by attempting to measure the distances of the moon and sun from earth by observing eclipses, it was necessary for Hipparchus to know the ratios of the sides of a right triangle.…

When had I just had a moment where it wasn't necessary to plan, or prepare for something, or think about fighting, or worry about the apocalypse?…

To experimentally measure the downward acceleration solely due to gravity at the surface of the earth and with negligible air resistance on a free-falling object, a piece of clear plastic with evenly spaced black bars, labelled as a “picket fence,” was suspended from a string and dropped through a Photogate sensor. This software is used to measure the actual acceleration of gravity to compare it to the value provided by literature review. The Photogate sensor transmits an infrared beam of light to a detector across a gap. It then determines and records data when the beam of light is blocked by an object. The part of the picket fence that blocks the beam of light in this experiment is the black bars.…

The two-point threshold experiment is meant to test a person's ability to perceive details on different parts of the body. Measurements varied on regions of the body depending on the size of their receptive fields. While the distance of the two points on my forearm was about three and a half centimeters, the distance between them on my upper arm was just barely four centimeters. Another example would be between my finger and thigh.…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the subject.…

Abstract : This paper presents a practical implementation for simulating the pitching and yawing motions of an autonomous underwater vehicle (AUV) and its consequent control using an ARM based SBC Friendly ARM mini2440. A rotary encoder and adxl303 triple axis accelerometer has been used to measure the position and acceleration respectively. The emphasis of this paper is given on the interfacing of the sensors with Friendly ARM mini2440 and the resultant control algorithm implemented on the embedded platform to control the designed testbench. The control algorithm implemented is PID control. It is to be noted that the entire project was done to study the movements of an underwater vehicle and the ensuing control strategies and the prototype…

Single tracker accuracy distribution Depth accuracy means the difference between the true depth value and the average value of the measured depth values corresponding with a planar surface located in front of a Kinect v2. As shown in part A in the figure blow (See figure 3.2, page 17), the depth values inside the light blue circle are captured by a Kinect v2 representing a planar surface and a average depth value is calculated as the center of the circle. The difference between the mentioned average depth value and the true depth value is defined as depth…
