In this experiment, three timers were employed to ensure precision and consistency in timekeeping. By synchronizing their efforts, the timers were able to record the duration of each object's descent with a high degree of accuracy, enabling researchers to derive meaningful insights into the gravitational behavior of the objects under study.
Measuring Tape: The measuring tape serves as a crucial instrument for determining the initial height from which the objects are dropped. By extending the measuring tape vertically and securing it in place, researchers can precisely measure the height from which the objects are released, thereby providing essential data for calculating the gravitational acceleration experienced by the objects during free fall.
Golf Balls: Golf balls serve as the primary objects of study in the free fall experiment. Their relatively compact size and uniform shape make them ideal candidates for investigating the effects of gravity and air resistance on falling bodies. By using golf balls of consistent mass and composition, researchers can control for variables that might otherwise confound the experimental results, thereby enhancing the reliability and validity of the findings.
Pen or Pencil: Pens or pencils are essential tools for recording observations, measurements, and other pertinent data during the experiment. By documenting the experimental procedure in real-time, researchers can ensure the accuracy and integrity of the data collected, thereby facilitating subsequent analysis and interpretation.
Worksheet: The worksheet serves as a structured framework for organizing and recording the experimental data obtained during the free fall experiment. By providing designated spaces for recording variables such as time, distance, and object type, the worksheet enables researchers to systematically capture and analyze key aspects of the experimental process, thereby facilitating the generation of meaningful insights and conclusions.
Futsal Balls: Similar to golf balls, futsal balls are employed as test objects in the free fall experiment. Their larger size and different composition compared to golf balls introduce additional variables for consideration, allowing researchers to explore how factors such as mass, surface area, and aerodynamic properties influence the behavior of falling bodies. By incorporating multiple types of objects into the experiment, researchers can gain a more comprehensive understanding of the underlying principles governing free fall dynamics.

Experiment Setup

The experiment was conducted with the following roles assigned:

Timer A
Timer B
Timer C (ball collector)

Procedure

The procedure outlined for the free fall experiment is meticulously designed to ensure consistency, accuracy, and reliability in data collection, enabling researchers to draw meaningful conclusions about the gravitational behavior of objects in motion.

Height Measurement Preparation: The procedure commences with Timer C dropping the measuring tape from the predetermined height of the building. This step is crucial for establishing the initial height from which the objects will be released. As Timer C drops the measuring tape, the ball collector stationed downstairs carefully notes the height, ensuring that an accurate measurement is obtained.
Timekeeping Setup: Following the height measurement, all timers prepare to record time. This preparatory step involves synchronizing the timers' devices and ensuring that they are ready to commence timing as soon as the objects are released. By coordinating their efforts, the timers minimize the risk of timing discrepancies and ensure that accurate time measurements are obtained throughout the experiment.
Object Release and Time Recording: Timer A assumes the responsibility of releasing the basketball, initiating the start of the timing process. As Timer A drops the basketball, Timer B and Timer C simultaneously begin recording time until the ball reaches the ground. This coordinated effort allows for precise time measurements to be captured, capturing the duration of the ball's descent with a high degree of accuracy.
Repetition and Data Collection: The experimental process is repeated three times for each type of object, ensuring that multiple data points are collected to enhance the robustness of the findings. By replicating the experiment multiple times, researchers can identify any potential outliers or inconsistencies in the data and ensure that the results are reliable and reproducible.
Analysis and Retrieval: Once the experimental trials are completed, the ball collector retrieves the basketballs and golf balls for further analysis. This step involves gathering the objects and preparing them for examination, allowing researchers to conduct a comprehensive assessment of the experimental outcomes and derive meaningful insights into the behavior of the objects during free fall.

Overall, the procedural steps outlined for the free fall experiment are carefully designed to minimize sources of error and ensure the integrity of the data collected. By adhering to these standardized procedures, researchers can conduct a rigorous and systematic investigation into the principles of gravity and acceleration, advancing our understanding of fundamental physical phenomena.

Analysis

The data collected revealed that both heavy and light objects resulted in similar outcomes. The average time and calculated distance for heavy objects were slightly higher than those for light objects. This disparity could be attributed to factors such as air resistance and human error in time and height measurements.

According to Galileo's experiment, objects of different masses fall at the same rate under gravity. However, in real-world scenarios, factors like air resistance can lead to slight discrepancies in results.

Conclusion

In conclusion, the free fall experiment conducted provided valuable insights into the fundamental principles of gravity and acceleration, shedding light on the behavior of objects in motion under the influence of gravitational forces. Despite the experiment's success in demonstrating the principle of free fall, it also unearthed several areas for improvement, primarily concerning measurement accuracy and procedural execution.

One of the key observations from the experiment was the identification of discrepancies in measurement accuracy, particularly in height measurements and timekeeping. These inaccuracies can be attributed to various factors, including human error, equipment limitations, and environmental conditions. Addressing these issues is imperative to enhance the reliability and validity of future experiments.

To improve measurement accuracy, researchers should consider implementing measures such as conducting multiple height measurements from different vantage points to account for potential discrepancies. By obtaining multiple height readings and averaging them, researchers can mitigate the impact of measurement errors and obtain more precise estimates of the initial height from which the objects are released.

Furthermore, precise timekeeping is essential for accurately capturing the duration of the objects' descent during the experiment. To achieve this, researchers should employ advanced timing devices with high precision and synchronization capabilities. Additionally, implementing standardized protocols for timing initiation and termination can help minimize timing errors and ensure consistency across experimental trials.

Another area for improvement highlighted by the experiment is the need to minimize the effects of air resistance on the falling objects. Air resistance can introduce variability in the objects' descent trajectories, leading to inaccuracies in the calculated results. To mitigate this effect, researchers can explore methods such as using streamlined objects with minimal air resistance or conducting experiments in controlled environments with reduced air resistance.

Moreover, enhancing procedural rigor and standardization is crucial for minimizing potential sources of error and ensuring the reproducibility of experimental results. By adhering to standardized procedures and protocols, researchers can minimize variability between experimental trials and enhance the reliability of the findings.

Recommendations

Conduct multiple height measurements to ensure accuracy.
Improve timekeeping accuracy during the experiment.
Have additional personnel on the ground to signal when the object hits the ground.
Use objects with different masses but similar surface areas to minimize air resistance effects.

Overall, while the experiment affirmed the principle of gravitational acceleration, human errors and environmental factors influenced the results to some extent. By addressing these limitations, future experiments can yield more accurate and reliable data.
