✅ Comprehensive General Answers

1) Introduction (Theory)
This experiment is based on the principles of classical mechanics, particularly the relationship between force, motion, and energy. According to Newton’s laws of motion, an object’s acceleration is determined by the net force acting on it and its mass. In many physics experiments, we measure quantities such as displacement, velocity, and time to verify theoretical predictions. A common formula applied is $F=ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration. Another useful relationship is the kinematic equation:

s=ut+12at2s = ut + \tfrac{1}{2}at^2s=ut+21​at2

where $s$ is displacement, $u$ is initial velocity, $a$ is acceleration, and $t$ is time. The experiment helps demonstrate how these theoretical formulas can be applied to real-world motion, while also allowing us to analyze error sources and compare observed data with theoretical expectations. Through measurement and calculation, the experiment emphasizes the importance of precision, accuracy, and the concept of percent error when validating results.

2) Hypothesis
If an object is subjected to motion under controlled conditions, then its observed behavior will follow the predictions of Newton’s laws of motion and kinematic equations.

3) Analysis (General Example)

• Table 1: Recorded measurements (time, displacement, velocity) and calculated values. Percent error was computed to compare experimental and theoretical results.

• Table 2: Repeated trials to improve accuracy and check consistency. Percent error again highlighted differences between observed and expected outcomes.

• Chart/Plot: A graph of displacement vs. time showed a parabolic trend, confirming constant acceleration. A velocity vs. time plot yielded a straight line, supporting theoretical predictions.

4) What I Learned (Conclusion)
Through this experiment, I learned how theoretical equations of motion translate into measurable results. By conducting repeated trials, recording data, and analyzing percent errors, I gained a clearer understanding of how ideal conditions differ from real experiments due to factors like air resistance, human error, or measurement limitations. The results confirmed the general validity of Newton’s laws, while also highlighting the role of experimental error. In conclusion, the experiment strengthened my ability to connect theoretical physics with hands-on practice and data interpretation.

5) Results vs. Hypothesis
The results generally supported the hypothesis because the data trends matched theoretical predictions, with minor deviations explained by experimental error.
