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?

About this app
What Makes a Force Bigger? is an interactive middle school physics app for exploring gravity, spring force, and friction. Choose objects and locations to compare mass and weight on the Moon, Earth, and Jupiter, adjust springs and hanging weights to measure stretch, and test how floor roughness and load affect friction. Four guided missions in each section help learners discover the rules behind each force.
Use cases
- Middle school students learning introductory physics
- Teachers demonstrating force concepts in class
- Parents guiding hands-on science practice at home
- Learners reviewing gravity, elasticity, and friction
Features
- Compare mass and weight for a watermelon, backpack, or dog on the Moon, Earth, and Jupiter
- Complete gravity missions involving target weights from 10 N to 750 N
- Choose soft, medium, or stiff springs and vary the number of hanging weights
- Measure spring stretch in centimeters through four guided missions
- Test friction on ice, wood, or rock with different loads
- Compare wide and narrow box sides to observe the modeled effect of contact area
