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:

$\tfrac{1}{2}at^2$

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.

1) Introduction (Theory)

This experiment aims to verify Newton’s Second Law of Motion, which states that the force acting on an object is equal to the product of its mass and acceleration, expressed by the formula:

$F = ma$

Where:

$F$ = Net Force (Newtons, N)
$m$ = Mass of the object (kilograms, kg)
$a$ = Acceleration (meters per second squared, m/s²)

The theory predicts a direct proportionality between applied force and acceleration when mass is constant. In practical experiments, factors like friction and air resistance must be minimized or accounted for, as they introduce deviations from ideal behavior. Data will be collected by applying varying forces to a cart of fixed mass and recording the resulting acceleration. Comparing theoretical acceleration (calculated from force and mass) with experimental values (measured) allows us to analyze the law’s validity through percent error evaluation. A small percent error would indicate experimental confirmation of Newton’s law.

2) Hypothesis (If/Then Statement)

If the applied force on a constant mass increases, then the object’s acceleration will increase proportionally, confirming Newton’s Second Law.

Post-Lab Section

3) Data Analysis (Sample Explanation)

We recorded the applied forces and measured the acceleration using motion sensors. The theoretical acceleration was calculated using:

$atheoretical=Fma_{theoretical} = \frac{F}{m}$

The experimental acceleration was determined from velocity-time graphs. Percent error was calculated using:

$Error=∣aexperimental−atheoretical∣atheoretical×100\% \, \text{Error} = \frac{|a_{experimental} – a_{theoretical}|}{a_{theoretical}} \times 100$

Data tables (Table 1 and Table 2) present values of force, mass, acceleration (theoretical and experimental), and calculated percent errors.
