Understanding the concept of balanced and unbalanced forces is fundamental to the study of physics. To illustrate these concepts, students of IGCSE Yr-1 physics conducted a simple yet effective experiment using a metre rule, a set of slotted masses, and a prism. This experiment has helped students visualize how forces interact and how equilibrium is achieved or disrupted.
The objective of this experiment was to demonstrate the principles of balanced and unbalanced forces by placing slotted masses on a metre rule that is balanced on a prism. By observing how the metre rule responds to different mass configurations, students understand how forces and torques interact to create equilibrium or imbalance. Such hands-on experiments provide a clear and tangible way to grasp fundamental physics concepts, making them valuable educational tools. It also let them explore the mathematical relationships governing torque and equilibrium by calculating and predicting outcomes before performing the experiment.
