Exercise
Reducing and Increasing Friction
In this engaging hands-on exercise, students will explore the concepts of friction by experimenting with various surfaces and materials to either reduce or increase friction, ultimately discovering how these forces impact motion in real-world scenarios. Through measurement and observation, learners will develop critical thinking skills as they design and test their own friction experiments!
