What Makes Force Grow?

⚖️ Would you really weigh less on the Moon? Place a 30 kg object on the Moon, Earth, and Jupiter in turn. Its mass stays exactly the same, while the scale reading rises and falls. Only its «weight» changes. 🪝 Add weights to a spring one at a time. Each one stretches it exactly 3 cm. That’s the secret behind how spring scales measure weight. 🧱 One last question: does a box slide more easily when laid flat? Try both the wide and narrow sides—the numbers don’t change at all. Friction depends only on «surface roughness» and «pushing weight». This app was made with code too · Shall we remix it to add buoyancy?‌
