Study Notes

Squashing and Stretching

Newton is the unit of force
Newton metre is the unit of force
Air resistance is a non-contact force
Magnetism is a non-contact force
Interaction pairs of forces

Force (N) vs Extension (mm)

1 N = 4 mm (extension)
2 N = 82 mm (extension)
3 N = 107 mm (extension)
4 N = 120 mm (extension)
5 N = 152 mm (extension)
The higher the force, the more the extension will expand
Starting length = 53 cm
