Lab Report must be typed. Lab report should be typed from the third person; in the passive form and in the past tense. Parameters for typed lab report: Font: Times New Roman, Size: 12 Line Spacing: 1.0 (The possibility to use the other programs rather than Microsoft Office to type lab reports can be discussed with the TA). Signed sheets with the experimental data must be submitted with the lab report. All graphs must be labeled. Lab report without the signed data sheets attached will automatically get a zero score. Lab Report includes the following parts. Each part should be clearly marked in the lab report: Title page (1 point): Name of the experiment; Student’s name (prominent); lab partners’ names; Group Number (number attached to the lab computers); TA’s name; Section number (SLN/class number from ASU catalog). Objective section (3 points): It is a statement of what physics concepts/theory/law was investigated or tested. What physics quantities had to be measured? It is one or two sentences. Experimental Data (3 points): only data that will be used in the further calculations. The experimental data should be tabulated. Tables should have appropriate headings and contain units. Data analysis section (10 points): contains calculations of the the physics quantity that needs to be found to achieve the lab objective. All intermediate calculations have to be present with the equations. Equations to calculate uncertainties of the experiment should be also present. Microsoft equation is one of the programs that can be used for typing the equation. Other programs are also permitted. Results section (3 points): Only Final Lab Results must be tabulated and reported in this section. Results include only the physics quantities that were stated to be found in the objective.Results do not include raw data and/or intermediate quantities. The final results should be organized in clearly labeled tables with their errors (if applicable). Results and uncertainties have to be reported with the correct number of significant figures and appropriate unit. Discussion and Conclusion section (10 points): This is one of the most important part of the lab report. Begin discussion with the purpose of the experiment. Briefly explain the physics theory/concept that was tested. State only the key/final results (with uncertainty and units) quantitatively with numerical values; does not provide intermediate quantities. Briefly explain the procedure that was used to collect the experimental data. Describe difficulties and shortcomings that were encountered during the experiment and it caused the uncertainties in the final results. Discuss “statistical errors” that affect your measurements, but which you can't do anything about given the time and equipment constraints of this laboratory. Suggest experimental redesigns to eliminate and overcome these troubles. Include a description of sources of “systematic errors” in your measurement that bias your result (e.g. friction in pulleys that are assumed frictionless in the formula). Describe the qualitative effect of each source of error (e.g. friction slowed motion, causing a smaller value of acceleration to be measured). Describe only the prominent sources of error in the experiment. Address questions such as: Are the deviations in the experimental results due to uncertainty in the experimental method, or are they due to idealizations inherent in the theory (or both)? If the deviations are due to experimental uncertainties, can you think of ways to decrease the amount of uncertainty? Discuss how the apparatus could be redesigned to reduce uncertainties or to streamline experimental technique. If the deviations are due to idealizations in the theory, what factors has the theory neglected to consider? All questions from the Lab Manual should be also answered in the discussion section. The conclusion made if the objective of the experiment achieved. Overall the full lab report is expected to be about 4 pages+ title page.

APA format/ 1 page and reference page Identify a current problem in physics by searching for news articles and current events. One reputable source of news in physics is Phys.org. Choose one article, and in two pages, describe how the scientific method is being used to solve the problem mentioned in the article. Identify the initial observations that identified the problem, the hypothesis, tests, and any revisions of the original hypothesis. Cite the article in APA format as well as other references you might use.
A spring is hanging down from the ceiling, and an object of mass m is attached to the free end. The object is pulled down, thereby stretching the spring, and then released. The object oscillates up and down, and the time T required for one complete up-and-down oscillation is given by the equation T = 2sqrt(m/k), where k is known as the spring constant. What must be the dimension of k for this equation to be dimensionally correct?
