PHYS2010/PHYS2020 Project Guidelines The purpose of this project is to use

The purpose of this project is to use the physics you have studied in PHYS2010/PHYS2020 to describe an everyday human activity that you will participate in. Your project must include: an abstract summarizing what you did and the results obtained; an introduction explaining why you chose the activity and detailing the physics involved, including all relevant equations; a short video documenting your activity that can be played on any device; a detailed, itemized list showing how you gathered data from the video; a data table with appropriate headings and units; an analysis demonstrating how you used the data to arrive at your results; and a conclusion discussing what you learned about the activity, how physics helped your understanding, and potential extensions of the activity that physics can predict.

Paper For Above instruction

Understanding the physics behind everyday human activities offers valuable insights into the application of fundamental principles in real-life scenarios. This project aims to bridge theoretical physics with practical observation by selecting a common activity, analyzing its physical aspects, and demonstrating the principles through data collection and analysis.

Introduction

The motivation behind choosing this project stems from the desire to witness physics in action and to enhance comprehension of core concepts such as kinematics, dynamics, and energy transfer. For instance, selecting an activity like jumping, running, or throwing a ball allows exploration of concepts like velocity, acceleration, force, and conservation of energy. By analyzing these aspects, we can better understand how physical laws govern seemingly simple actions, thus fostering a deeper appreciation for physics' relevance.

The core physics principles involved include Newton's laws of motion, equations for velocity and acceleration, kinetic and potential energy calculations, and possibly rotational mechanics if applicable. The relevant fundamental equations include:

• Velocity: \( v = \frac{\Delta s}{\Delta t} \)
• Acceleration: \( a = \frac{\Delta v}{\Delta t} \)
• Kinetic Energy: \( KE = \frac{1}{2}mv^2 \)
• Potential Energy: \( PE = mgh \)
• Newton's Second Law: \( F = ma \)

These equations form the backbone of the analysis, enabling quantification of the activity's physical parameters from observed data.

Methodology

The activity was recorded using a smartphone camera, capturing all stages of the process. The video was then carefully analyzed frame by frame to extract positional data at specific time intervals. An itemized list was compiled to detail information such as frame rate, reference points identified within each frame, and timings of key events (e.g., takeoff, peak height, landing).

Data extraction involved measuring distances traveled in the video and converting pixel measurements into real-world units using a known reference object within the frame. The data table was constructed to include columns for time, displacement, velocity, and acceleration with units specified, thus ensuring clarity and precision in subsequent analysis.

Data and Analysis

The recorded data enabled calculations of velocity and acceleration at different points of the activity. For example, by measuring displacement across frames and dividing by the time elapsed, velocities were obtained. Changes in velocity over time informed acceleration calculations. Using energy equations, the maximum height reached and initial velocity could be estimated, demonstrating the conservation of energy principle.

As a specific example, in analyzing a jump, the initial velocity at takeoff was deduced from the maximum height achieved, applying the energy conservation law: \( v_0 = \sqrt{2gh} \). The results were then compared with actual measurements from the video data to verify consistency. Calculating forces using \( F=ma \) allowed further insight into the muscular effort involved during the activity.

The analysis showed how small differences in initial conditions affect the overall outcome, aligning with theoretical predictions. The physical parameters derived from the data validated fundamental physics equations and reinforced their applicability.

Conclusions

Through this activity, the integration of theoretical physics with practical observation has significantly deepened understanding. The close match between calculated and observed data affirms that fundamental physics principles reliably describe everyday activities. Moreover, this project highlighted the importance of precise data collection and analysis in experimental physics.

The activity demonstrated that physics tools can effectively predict outcomes beyond simple textbook examples. For instance, by applying conservation of energy and Newton's laws, it is possible to forecast outcomes like jump height or the force exerted by muscles during movements. Future extensions could involve exploring rotational motions or investigating effects of different surface conditions, thus broadening the scope of physics applications in real-life contexts.

Overall, this project elucidated how physics manifests in daily life and sharpened skills in measurement, data analysis, and critical thinking—fundamental competencies for any physicist or scientist.
