Spring Scale Physics Demo by Avantor

Budget-friendly, Simple, Enjoyable: Showcase these physics demos to captivate your students. Setup and operation are straightforward, allowing more time for student interaction. Perfect for introducing topics or reinforcing lessons, these demos cover all basic physical science subjects. Two 70 cm long spring scales let students observe and demonstrate force experiments and balance. A centrally hung mass causes equal spring displacement, while an off-center mass results in varied elongation. Easy displacement measurement using the tube's metric scale. Includes two large spring scales, a connecting rope with hook, and a comprehensive demonstration guide. Each spring has a constant of approximately 78 N/m. Masses not included.
