Plotting Electric Potential Lab
Purpose: To understand and experiment with electric potentials and examine electric fields, from their directions to their strengths and their behavior. Also, to map electric equipotential lines and electric field lines for two-dimensional configurations.
Procedure: Starting the first of two parts of our lab (part A), we began by setting up our equipment. We first set up our conducting paper and pushed two aluminum push pins into each of the two conducting metallic holes on the paper. We then followed by connecting the negative terminal of the power supply to the push pin on the left and the positive terminal to the opposite push pin on the right (see figure below).

After everything was set up we turned the dial of the voltmeter to 20 Volts (V), and proceeded by pushing the tip of our probe in the middle of the conducting paper and adjusted the DC power supply until the voltmeter read 5.00 V. Once we got an accurate reading, we gently used the probe to find points on the conducting paper that also read 5.00 V, generally about 2 cm above the starting position. We proceeded with this technique until we reached the apex of the y coordinate, which was capped at 20.0 cm. Following completion of the superior part of the x-axis, we took our probe and repeated the same procedure for the inferior portion of the x-axis, which extended down to 0 cm. We continued this process for the y-axis as well and also plotted curves ranging between 1.00-8.00 volts and upon completion, our conducting paper had multiple equipotential lines.
For the second part of our lab (part B), we repeated the same identical steps as part A, only the end result was a sketch that revealed equipotential lines that were much more compact, shortening the electric field in comparison to part A.
Results: The results show us that it is expected that the electric field lines run perpendicular to the electric potential lines in experiment A, solidifying a uniform electric field. Meanwhile, experiment B demonstrated how the electric field lines can shift and shorten (more compact) with the electric potential when surrounding a point charge. Additionally, we learned that the data points along the electric field line show how the magnitude of the electric field is calculated from the electric potential.
Calculation:

Conclusion: This experiment adequately addressed the relationships between electric field magnitudes and electric potential as it allowed us to compute the electric field magnitude using the data we gathered from experiments A and B. The experiments showed how the different types of charges associated with the electric field produce varied electric field lines and equipotential lines. In the first experiment, the circular pattern produced from a point charge by the electric potential lines are a nice contrast to our second experiment, where the charge distribution produced a uniform electric field that had nearly straight vertical lines and nearly straight perpendicular electric field lines associated with them. In conclusion, this experiment proved the definition of equipotential lines, where if you move perpendicular to the electric field, the potential does not change.

Master Schedule

...THE MASTER SCHEDULE Any plan to schedule time and activities must have at its center a MASTER SCHEDULE, that is, a schedule of activities that is fixed. A master schedule needs to be drawn up only once a semester: unless, of course, changes occur in the basic program. First, fill in all the required activities, such as classes, drills, and laboratory periods. Second , add other regular activities, such as part-time jobs, commuting time, sports, and regular meetings. Third, include sleeping and eating. With the fixed activities accounted for, the remaining blank spaces on the uncluttered chart are free for use on a weekly or day-by-day basis. Such a schedule, on a 5x8 card, scotch-taped over your desk, or carried in your notebook, unclutters your mind, and more important, enables you to visualize the blank boxes as actual blocks of time into which you may fit necessary activities (see example below). With the MASTER SCHEDULE as your source, you may concoct any type of schedule that fits the uniqueness of your courses, your part-time or full-time job, or your personality. What matters most is that the schedule works for you.

...response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) evaluates students’ shifts in epistemology and affect at the beginning and end of a semester. Also, at the end of the semester, the E-CLASS assesses students’ reflections on their course’s expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for PER research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also discuss feedback from instructors and reflect on the challenges of large-scale online administration and distribution of results. I. INTRODUCTION Laboratory courses offer significant opportunities for engagement in the practices and core ideas of science. Laboratory course environments typically have apparatus, flexible classroom arrangements, low student/teacher ratios, and opportunities for collaborative work that promote students’ engagement in a range of scientific practices...

...Yangyang Bian Phys 1101W Section 100 TA: Roxanne Radpour November 15, 2009 Lab 5 Problem #1 Kinetic Energy and Work Problem description and prediction: In this lab, we release a cart from different heights of the incline and then investigate how the final velocity depends on its initial release height and what the relation between the work and the change in kinetic energy. EK1=0 EK2=1/2mv2 The work is done by the x-component of gravity. W=mgsinθ×L=mgH ( unit is kg·m/s2·m=kgm2/s2) v2-0=2as v2=2as=2gsinθ×L=2gH v= (2gH)1/2 The final velocity depends on the height. It is not necessary related with the angle and mass. EK2=1/2mv2 (unit is kgm2/s2) EK2-EK1=1/2mv2-0=1/2m·2gH=mgH W=EK2-EK1 The work done by the gravity on the cart is equal to the change in kinetic energy. Procedure: 1. Practice: Vary track angles, release heights, and cart masses. And then release the cart form the rest. During each trial, measure the time when the cart reaches to bottom of the incline. 2. Vary release heights: Set the track angle which is 4.9° and the mass which is 190g. Release the cart from three different heights and take video for all of them.
