Answers:

1) Theory (Introduction)
This experiment explores the fundamental relationship between measured variables in a physical system—such as force, mass, acceleration, or energy—and how they conform to established scientific laws. For example, according to Newton’s Second Law of Motion, $F=ma$, force equals mass multiplied by acceleration. Each term represents measurable quantities: $F$ (force) in newtons (N), $m$ (mass) in kilograms (kg), and $a$ (acceleration) in meters per second squared (m/s²). Understanding this relationship helps explain how objects respond to applied forces and provides a basis for calculating expected outcomes. The experiment’s theory may also involve calculating percent error to evaluate the accuracy of experimental results compared to theoretical predictions, using the formula Percent Error=∣Experimental Value – Theoretical Value∣Theoretical Value×100text{Percent Error} = frac{|text{Experimental Value – Theoretical Value}|}{text{Theoretical Value}} times 100Percent Error=Theoretical Value∣Experimental Value – Theoretical Value∣​×100. This helps assess measurement reliability and overall precision.

2) Hypothesis
If the experiment follows the theoretical relationship between force, mass, and acceleration accurately, then the data collected will show that as mass increases (with constant force), acceleration decreases proportionally, confirming Newton’s Second Law.

3) Analysis
In the analysis section, data from tables and plots should display consistent patterns aligning with theoretical predictions. Graphs of force versus acceleration are expected to be linear, indicating proportionality. Any deviations can be attributed to measurement errors, frictional forces, or reaction time during data collection. Percent error calculations help validate accuracy.

4) What I Learned (Conclusion)
From this experiment, I learned how theoretical principles translate into measurable data. The experiment demonstrated how applying controlled conditions allows verification of known physical laws. By calculating percent error, I gained insight into the importance of accuracy and precision in data collection. Overall, the results strengthened my understanding of experimental physics and the relationship between theory and observation.
