Exercise
Form 4: Physics of Free-Falling Objects
In this engaging exercise, students will explore the principles of gravity and motion by conducting experiments with free-falling objects, measuring their fall times, and applying Newton's laws to understand acceleration and impact. Through hands-on activities and real-world applications, learners will deepen their comprehension of kinematics and the effects of air resistance on falling bodies.
