To use a spring scale, hang the object you want to measure from the hook at the bottom of the scale. The spring inside the scale will stretch or compress depending on the weight of the object, and the scale will show the corresponding reading on its display. Make sure to read the scale at eye level for an accurate measurement.

No, a spring scale is used to measure weight, not mass. To measure mass, you would typically use a balance scale or electronic scale. Mass is a measure of the amount of matter in an object, whereas weight is the force acting on an object due to gravity.
Weight is measured using a spring scale, which operates on the principle of Hooke's law that the force exerted on the spring is proportional to the displacement of the spring. The spring scale measures weight by the amount of force needed to stretch the spring within the scale.
To use a Newton spring scale, hang the object you want to measure from the hook on the bottom of the scale. Read the value where the pointer on the scale stops, which is the force exerted by the object in Newtons. Make sure to hold the scale vertically and at eye level for accurate readings.
The change in the spring scale reading is caused by the force applied to the spring. When an external force is applied to an object attached to the spring scale, the spring compresses or stretches, leading to a change in the scale reading which reflects the magnitude of that force.
The main difference between a 0-5 N spring scale and a 0-20 N spring scale is the range of forces they can measure. The 0-5 N spring scale measures forces from 0 to 5 Newtons, while the 0-20 N spring scale measures forces from 0 to 20 Newtons. This means that the 0-20 N spring scale can measure a wider range of forces compared to the 0-5 N spring scale.
