Did you learn anything else from the lab, such as use of lab equipment, procedures, analysis methods, etc. The voltage is the same when going through each resistor which follows the formula in parallel circuit that each voltage equals each other. The static coefficient of friction was found to be larger than the kinetic coefficient of friction in all cases. Procedure: The procedure is one of the top three important sections in the lab report. Data: Table 1-Using values of current and resistors to find voltage: can be found in the appendix A of this report. Conclusion: I can conclude that my results do agree with the theory. Lab report templates have been created to make the work of lab techs easy.
Present the raw data that you collected during your experiment in this section of the report, making sure that it is clearly organized and includes units of measurement. While writing skills may not seem related to science, it is actually critical that scientists be able to clearly articulate their methods and conclusions. Stick to the third person. Friction is a force that must be overcome before an object can move across a surface. Graphs are not an analysis.
However, for voltage and resistance when one increases so does the other. . Mention the particular pitfalls in data taking that you discovered and managed to maneuver around. Friction Lab report Essay Sample This experiment measures the coefficient of static friction μs and kinetic friction μk between objects of different materials. Data should be recorded in a neat and orderly fashion, either on data tables provided in a lab handout, or in tables you create for the activity. A truly formal lab report must have a separate title page, but in general this is wasteful.
It is the mass per unit volume of a substance. Sample physics labeport format bahamas schools simple harmonic motion pendulum ib. It is also important to label any charts, tables, or figures you include in your report so that you can refer back to them and your readers will know where to look. Make sure you have answered all analysis questions, and you have answered your research problem as posed in the introduction. If you used the equation multiple times throughout the experiment, you only need to write out one example. In scientific community, a lab report template is the guidance needed by any researcher where they can have a sensible result of their experiment or research whether it supports their study or not. Both of the percent discrepancies for the elastic collisions were less than the percent discrepancies in inelastic collisions which validates the concept of energy conservation to be more efficient in elastic collisions.
Sample physics lab report for ib simple pendulum example. Both of the percent discrepancies for the collisions were close to the 10%-15% range which validates the concept of momentum conservation in inelastic and elastic collisions. It is unlikely, however, that this measurement technique biased our results, since the technique probably gave measurements of C that were too high in some cases and too low in others. It will be helpful to you during the actual performing of the experiment and also when you write your lab report. Possible error in this lab may have resulted from the neglect of friction and rotational kinetic energy. If your raw data is illegible, the grade will suffer. The Air Track can be used to obtain an accurate investigation of the laws of motion.
This was accomplished by drawing an outline of the starting position. As the magnitude of F increases, fs will increase proportionally until is exceeded. There is quite a bit of experimental error involved with the measurements. Repeat the previous procedure, and interrupt the circuit in order to connect the multimeter at certain points in order to measure the currents of each resistor. The procedure or method section of your report should be a detailed explanation of exactly how you conducted your experiment. The same held true for μk, 0. Further graphing rules are listed in the Theory section of Experiment 1 and other graphical techniques are developed in Experiment 2 and 3.
However, it has been found experimentally that when two very smooth pieces of metal have been stacked together, given that all contaminates have been removed and they are placed in a vacuum, they become cold-welded and the coefficient of static friction is very high. The unit of moment is the Newton metre Nm. Was your hypothesis supported or contradicted, or were the results not sufficiently precise to allow you to say one way or the other? Each graph should convey a complete message and be fully understandable without referring to any other section in the report. Do not assume that science or an essay topic is too complicated for you to understand. Record the reading of I0 which is initial current. In the equation time will become less and change in momentum is directly proportional to time.
Report physics lab template sample format maggi locustdesign co example abstract simple harmonic motion. Graphs are especially useful for examining possible trends over the range of measurements. It is also expected that the coefficient of friction for the wood block would be the same whether the plank was flat or at an incline, but the difference between the two coefficients of static friction was 12. This is where all of the science is. When the block just starts to move, note the force on the spring scale and record.
Then, include an abstract, or summary of your report, followed by your objective, procedures, and methods. Be sure to do this with every resistor. In one experiment the wood block was placed on its side and the experiment repeated. The abstract is the first part of your report that your readers will see, but it should be the last thing you actually write because it is a summary of everything else you have included in your report. You may also enjoy this sample physics lab report trending images The front cover is not the only reason. The difference between the experimental values showed this to be true. In regards to conservation of energy, the calculations state that the percent discrepancies for inelastic collisions were 58.
The manner in which the block was placed also affected the outcome. A plain block of wood and a block of wood with sandpaper on one side and glass on the other were used. To study the effects of the normal reaction and surface area on the force of friction using a block. Keep in mind that the multimeter sensitivity should be at 200mA range. Next, write an analysis of your data, and a conclusion to explain what you've learned. Conversely, if a student did not contribute to the writing or analysis of the lab their name should not appear on the title page or in the title section. If your results differed from known values, how do you account for the error? Despite the exciting and extraordinary development of ideas throughout the history of physics, observations remain essential to the very core of the subject.
