Exercise
Classroom Demonstrations of Inertia
In this engaging exercise, students will participate in hands-on demonstrations to explore Newton's first law of motion, gaining a deeper understanding of inertia through practical experiments that illustrate how objects resist changes to their state of motion. From rolling balls to frictionless slides, students will actively observe and predict the behavior of various objects, fostering critical thinking and scientific inquiry.
