Types of Forces
by Anonymous
Compare mass and weight across the Moon, Earth, and Jupiter, then stretch a spring and switch contact surfaces to find what friction really depends on.

About this app
Types of Forces is an interactive middle school physics app for exploring gravity, spring force, and friction. Choose objects and locations to compare mass, gravitational strength, and weight on the Moon, Earth, and Jupiter; then test how different springs stretch under loads. A final friction activity lets you compare ice, wood, and rock surfaces, load weights, and box orientations through guided missions.
Use cases
- Middle school students learning about forces
- Teachers demonstrating mass, weight, and gravity
- Learners investigating spring extension and elastic force
- Students comparing friction on different surfaces
- Classroom or self-study science practice
Features
- Compare an object's weight on the Moon, Earth, and Jupiter while its mass stays constant
- Choose watermelons, backpacks, or dogs and view mass, gravity strength, and weight values
- Test soft, medium, and stiff springs with one to four hanging weights
- Measure spring stretch and complete proportional-extension missions
- Compare friction for ice, wood, and rock with different loads
- Test wide and narrow box faces to investigate whether contact area changes friction
