Product overview This stainless steel potential energy conversion experiment kit lets users observe kinetic and potential energy changes and the conservation of mechanical energy through a simple, handson apparatus. The polished components provide smooth motion so students and instructors can focus on demonstrating core physics principles. Key benefits Demonstrates fundamental physics: Visualize conversion between potential and kinetic energy and observe how total mechanical energy is conserved as the roller swings along the track. Educational and interactive: Designed for classroom demonstrations, lab experiments, and home STEM activities to make abstract energy concepts tangible. Durable construction: Made of stainless steel for longterm use and resistance to corrosion. Polished surfaces promote smooth motion and consistent results. Simple setup and operation: Place the roller on the track, adjust height and angle, then release. The kit is straightforward to use for demonstrations or repeated experiments. Adjustable variables for experiments: Vary initial height, track angle, and roller mass to study how each factor affects speed, maximum height, and energy distribution. Low maintenance: After use, apply rustproof oil to the roller as needed to maintain performance. Oil not included. Included items 1 x Wheel 2 x Riser 1 x Crossbeam 1 x Wire 1 x Base Function and performance The kit allows direct observation of how a swinging roller converts potential energy to kinetic energy and back while moving along a curved track. Because the components are smooth and well finished, motion is predictable and repeatable, enabling clear demonstrations of energy conservation and mechanical energy calculations. Users can record position, speed, and height over time to compare experimental results with theoretical expectations. Practical use scenarios Physics classroom demonstration: Show energy conversion and conservation during a lecture, then let students measure heights and speeds to calculate mechanical energy. Student lab experiment: Use the kit for handson lab work to test how varying initial height or mass changes kinetic energy and peak height, and to practice data collection and analysis. Home STEM activity: Provide a tangible way for learners to explore motion and energy through guided experiments and simple measurements using a ruler, stopwatch, and scale. Compatibility and care Suitable for use in classrooms, teaching labs, and home learning environments. Material: stainless steel. For performance, keep components clean and periodically apply rustproof oil to the roller and contact points. Oil not included. This kit provides a clear, durable, and reusable tool for demonstrating energy conversion and conservation without specialist equipment.
