Overall, the experimental results supported the theories on the coefficient of friction. Note that all lab reports may not have every section, but it is a good idea to include all of these sections even if you write no such-and-such required. Various types of materials were used, as well as horizontal versus inclined ramps. Theory These sections should be somewhat self-explanatory from their headings. Remember just one example of every equation used is to be shown.
Analysis: Note: As the semester progresses, you will be expected to take more and more responsibility for deciding how to analyze your data. These should be in the experimental procedures section. Physics Lab Report Outline Students are strongly encouraged to write their reports in the order detailed on the diagram above. Since α and remain constant and , the graph should resemble a straight line a linear function. Sample physics labort free fall simple pendulum experiment ap ib college. Then I drew a box by dragging on the screen. Tips and Hints for Effective Physics Laboratory Reports The Purpose of the Report is to Communicate Truth.
Also include who on your team did what during the experiment and for the report as appropriate recording data, organizing the team, performing particular tasks in the experiment, producing graphs, etc. A lab report can be written for a number of reasons from documenting the details of the laboratory test conducted on a patient in the laboratory to completion of an experiment. But you also must record here any changes you made, or variations in that procedure you chose to do, or had to do based on your equipment. Conclusion: This is the second most important part of the lab. Sanding the plank would have helped in this area, though.
For example, if you were measuring the conductivity of a metal bar, and measured the diameter as 5. Stick to the third person. After determining the values of the five resistors, disconnect the multimeter in order to connect a wire from the positive end to the resistor. Now the friction works against gravity, thus the acceleration of the cart when is going down should be less than what should be. The line has an intercept -0. The theory section contains definitions of terms, nomenclature, necessary formulas, wiring diagrams, equipment illustrations, and expected graphical results. However, using the graph and data, the value of was calculated, and Conclusion: Unlike the assumption in the hypothesis, the experiment showed that: As mentioned above, the origin of was not able to be determined.
Your goal for this part of the report is to allow anyone reading the report to duplicate your results. What are the Parts of a Lab Report? It can be seen as a clear trend that with increasing voltage the resistance also increases as they are directly proportional. With low values of change in momentum and kinetic energy that occurred in elastic collisions, it is understood that both are conserved in this type of collision. The data was collected and translated to a graphical model for further analysis. Analysis of graphs belongs in this section, such as which graphs yielded straight line correlations and what the slope of such a line might have been, and what that slope if it exists might mean.
Then change the length of the string 4 times, so that you get 5 different sets of results and for each time, repeat it 3 times. 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. In this experiment, relative density is also used to be able to determine the composition of the substances or objects used. Methods Materials: Ramp board, 4 feet long set at 10 cm off the ground. Analyze your results, looking for trends or patterns.
Two examples are as follows: 1. The second part consisted of how to use the variables in an electrical current. Rough objects had greater coefficients of friction than smoother objects. This may require a series of paragraphs where you describe the scientific principles you were modeling and give background historical and theoretical information. Can of soup 500-g spring scale Meter tape Friction block set one wood, one glass, one sandpapered Protractor Procedure:2 Part 1 1.
The coefficients for the wood on its side were lower than when the wood was on the side with the most surface area. Record the findings in tables similar to Data Table 3. Graphs and figures will appear here, and they must be clearly labeled, with any slopes or intercepts or regression lines and coefficients of determination included in the graph generated by software tools. The length of string was constant in all 3. Use full sentences and proper grammar.
