Exercise
Walking, Running, and Ground Friction
In this engaging exercise, students will explore the concepts of walking, running, and the role of ground friction in motion through hands-on experiments and interactive discussions, helping them to understand how different surfaces affect their speed and stability. Join us in uncovering the science behind your stride!
