In this project, I have to create a model as a group to meet the Newton's law which states the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. This relationship can be expressed by the equation F= ma, where F represents force, m represents mass, and a represents acceleration. To maintain the constant acceleration, when the mass increases, the force has to increase correspondingly.
Objective : To create a diy interactive lift & rotate model to visualize and verify Newton’s Second Law which states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated.
The force measured by the force meter is set as theoretical value. After that, the ruler is used to measure distance (in meter) and a timer to record time (in seconds) in order to calculate acceleration. The collected mass and acceleration is applied in the equation F= ma to find the practical value of the force. At the end, both theoretical value and practical value of the force is used to compare the relative error to verify the application of Newton's Second Law.
** The results are shown at the left**
The results verify Newton's second law as the mass times acceleration gives us a value very close to the actual force measured by the force meter.
My group consists of 4 people including me and we decided that we were going to move forward with the concept of Newton's Second law. In addition, I got the opportunity to lead the team which was connected to MUIDS ESLO's Leader of the Future. Moreover, we overcame numerous challenges after continuing our work. However, by developing into a Strategic Learner who can recognize issues and find the best solutions, I was able to advance with the team past that. Ultimately, we succeed in finishing this project at the end.

In Quarter 4, I had the opportunity to extend my understanding of Ohm’s Law and circuits by building four parallel circuits to visualize and verify the relationship V = IR. Each circuit included an LED (green, red, yellow, or blue), which acted as a resistor connected to a battery and a light switch. As we observed, LEDs are nonlinear, or non-Ohmic, meaning their resistance changes and cannot be measured directly using a multimeter. Instead, we calculated the apparent resistance using the equation V = IR. In the end, we concluded that while LEDs do not follow Ohm’s Law consistently due to their non-linear behavior, the law can still be applied point by point to describe their behavior at specific operating conditions.
This project encouraged me to become an Innovative Thinker by designing circuits that were clear and self-explanatory, which helped me better understand Ohm’s Law and develop the practical skills needed to build and analyze circuits. Additionally, I became an Articulate Communicator by actively participating in brainstorming sessions and collaborating effectively to complete the project on time.
