Exercise
Form 3: Pendulums and Roller Coasters
In this exhilarating exercise, students will explore the principles of energy transfer and motion through hands-on activities that simulate pendulum swings and roller coaster dynamics, allowing them to apply physics concepts in real-world contexts. Get ready to design your own roller coaster model and observe how different angles and heights affect speed and energy!
