Spring balance is used to measure the weight of the body.
Everything is composed of matter, and the quantity of matter that makes up a body is referred to as its mass, whereas the gravitational attraction that a body experiences is referred to as its weight.
The amount of the force of gravitational attraction acting on the body is referred to as the weight of that body.
A spring balance is used to determine the weight of an object.
Spring can be found within a spring balance.
This spring has a hook connected, from which the spring balance's body hangs.
The weight of the object being weighed is displayed on the graduated scale as it is hanging from the hook.
The spring balancing operates under the principle that states that the weight of a body attached to its hook is directly inversely proportional to the spring's extension.
Therefore, the extension increases with weight while decreasing weight decreases the extension.
