Forced Vibration and Resonance Demonstrator Kit for Physics Lab, Pendulum Ball Type Demonstrator With Five Steel Balls, External Force Vibration Demonstrations, Hands-On Classroom Demo Equipment

Forced Vibration and Resonance Demo Kit with Pendulums
✔️ Five pendulum-length steel balls on a plastic frame, rigid and ready

The demonstration kit is a hands-on physics teaching tool designed to visualize how external forces drive motion, causing forced vibration and resonance in pendulum systems. It's ideal for classrooms, labs, and display boards where quick, tangible demonstrations help students grasp core concepts.

✅ Five pendulum-length steel balls enable varying resonance tests
✅ Plastic frame keeps the setup stable on desktops or lab benches
✅ Includes external force vibration demonstration to show drive and response
✅ Compact, durable kit suitable for teaching displays and hands-on demos
