Coupled Pendulum Model

Coupled Pendulum Model – Energy Transfer Demonstration | Manufactured by Samtech Instruments

The Coupled Pendulum Model by Samtech Instruments is a physics demonstration apparatus designed to explain energy transfer, resonance, and oscillatory motion. Widely used in school and college laboratories, it visually shows how motion passes from one pendulum to another.

Description
The model consists of a mild steel metal frame supporting a wooden rod fixed securely using thread. Two pendulums are suspended from the rod at equal distances from the centre, allowing interaction between their oscillations.

Working Principle
When one pendulum is set into motion, its energy gradually transfers to the second pendulum through the connecting support. The first pendulum slows down while the second begins oscillating. This alternating exchange continues, demonstrating coupled oscillations in a near frictionless system.

Educational Concept
The apparatus explains energy conservation, resonance, wave behaviour, and vibration transfer. Students can clearly observe how motion shifts between objects without direct contact.

Educational Applications
Ideal for classroom demonstrations, laboratory experiments, and science exhibitions. Helps students understand oscillation theory and real‑life examples like bridges, buildings, and mechanical vibrations.

Key Features
🔄 Demonstrates transfer of energy between pendulums
🛠️ Strong mild steel frame construction
📏 Equal‑distance suspension for accurate results
🎓 Useful for physics labs and STEM learning
🌐 Explains resonance and vibration behaviour clearly
