Exercise
Free Fall and Air Resistance
In this engaging exercise, students will explore the dynamics of free fall and the concept of air resistance through hands-on experiments and simulations, allowing them to observe how different shapes and materials affect the rate of descent. Through observation and analysis, students will deepen their understanding of gravity, forces, and the interaction between objects in motion.
