✅ Comprehensive General Answers

1) Introduction
This experiment focuses on the application of Newtonian mechanics to real-world observations. The core theory lies in understanding motion, forces, and measurement accuracy. Newton’s Second Law of Motion, $F=ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration, is fundamental to predicting how objects behave under specific conditions. Another relevant formula is the kinematic equation for free fall:

d=12gt2d = \frac{1}{2} g t^2d=21​gt2

where $d$ is displacement, $g$ is gravitational acceleration (9.8 m/s²), and $t$ is time. In experimental physics, measurements often contain errors; hence, calculating the percent error is essential:

% Error=∣Experimental Value – Theoretical ValueTheoretical Value∣×100\% \, \text{Error} = \left| \frac{\text{Experimental Value – Theoretical Value}}{\text{Theoretical Value}} \right| \times 100%Error=​Theoretical ValueExperimental Value – Theoretical Value​​×100

This ensures accuracy assessment. The experiment not only reinforces theoretical knowledge but also develops skills in data collection, error analysis, and scientific reasoning.

2) Hypothesis
If objects of different conditions (such as varying mass or shapes) are tested under the same experimental setup, then their observed outcomes will follow Newtonian predictions, with any discrepancies explained by experimental errors.

3) Analysis (General Format)
A proper analysis includes tables of recorded values (distance, time, mass, etc.), calculated percent errors, and graphical representations such as displacement vs. time plots. For instance:

• Table 1: Recorded and theoretical values, with percent error calculation.

• Table 2: Second set of results with errors computed.

• Graph: Linear plot showing the relation between measured variables.
  These tools help visualize deviations between experimental and theoretical expectations.

4) What I Learned
From this experiment, I learned the importance of careful measurement and the role of theory in predicting outcomes. The data showed that even though the theoretical models provide exact predictions, experimental limitations such as reaction time, friction, and equipment precision introduce slight errors. By comparing measured results with theoretical values, I gained a deeper understanding of accuracy, reliability, and scientific reporting. Overall, the lab strengthened my ability to connect physics concepts with real-world applications and highlighted the significance of percent error in validating results.
