A spring balance is a simple instrument commonly used to measure what physical quantity?

Explanation

A spring balance is a simple instrument used to measure weight, or more precisely the force exerted on it, by measuring how much an internal spring stretches or compresses in response to an applied load, based on the predictable relationship between force and spring extension. Because the spring’s extension is directly related to gravitational force acting on an object, a spring balance’s reading can be affected slightly by variations in local gravity, unlike a standard balance that compares mass against known reference weights. Spring balances are commonly used in simple classroom science experiments as well as certain practical applications, such as some fishing scales.
