Description
A Newton spring balance (also called a spring scale or force meter) measures force by how much it stretches an internal spring — you hook or hang an object on it and read the force in Newtons on a scale.
A 3-pack set with 1N, 2.5N, and 5N capacities is a common intro-physics/classroom kit:
- 1N – for very light objects (small weights, light springs, low-force experiments)
- 2.5N – mid-range, general classroom use
- 5N – heavier objects, higher-force demonstrations
Having three ranges lets students measure a wider variety of objects accurately, since a spring scale is most precise near the middle-to-upper end of its range (a 1N scale maxed out on a heavy object would be inaccurate, and a 5N scale on a very light object won’t show much movement).
They’re typically made of a clear plastic tube housing, a coil spring, a sliding pointer/scale, and a hook on each end — used for teaching Hooke’s Law, gravity/weight, and basic force measurement in middle/high school science curricula.
