A physics lab report is typically divided into five sections consisting of the abstract, the introduction or statement of purpose for the lab experiment, a description of the experiment's procedure, the actual results including data collected and the conclusions drawn from the experiment. These are fundamentally the same sections that appear in most scientific papers but shortened somewhat for student lab reports.
The abstract in a physics lab report is a brief summary of what was measured in the physics experiment, what procedures were used and the final results. The introduction explains the theory behind the experiment, the reason the measurements were taken and any equations involved. The procedure section of a physics lab report describes exactly what was done in the experiment. It includes a description or diagram of all equipment used.
The results section of a physics lab report is the most important part of the report. It presents all findings, including all data collected. In some physics classes, teachers ask students to provide the raw data gathered during the experiments so they can try to calculate the results themselves. Data should also be presented in neat charts and tables. The results section also explains the significance of all results obtained and should include any errors made.
The final section of a physics lab report is the conclusion section, which explains what conclusions can be drawn from the experiment. The conclusion section should also show the relationship between the results of the experiment and the theoretical predictions that were made before the experiment began.
