# What can a spring scale measure?

## What can a spring scale measure?

A spring scale in equilibrium can measure weight. Weight is the gravitational force acting on an object. Weight is proportional to mass.

## What is spring balance on what principle does it work?

Hooke’s law
Spring balance works on the principle of Hooke’s law. Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.

When should the reading on a spring balance be taken?

Explanation: They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness. A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.

How does spring balance measure force?

Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.

### Is spring balance used to measure weight?

Spring balance is a mechanical device used for measuring the weight or force of an object by opposing the force of gravity with the force of an extended spring. Note – Spring balance measures the weight of an object but not used for mass.

### Why is spring balance used in this activity What do you infer from this activity?

A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extending spring. May be used to determine mass as well as weight by recalibrating the scale.

What does spring balance records?

A spring balance measures the weight of an object by opposing the force of gravity acting with the force of an extended spring.

What is the reading of a spring balance?

The reading of the spring balance is the pulling force on it divided by the acceleration due to gravity \$g\$.

## What is a spring balance used for Class 8?

Class 8 Question Spring balance is a device used to measure the weight of small bodies. I t consisits of a spring to hang the weights. As the weigths are hung to the spring it stretches the the pointer indicates the weight hung or the force applied on the spring.

What do we measure with spring balance?

Weight of a body is measured using a spring balance. A spring balance has a spring inside. A hook is attached to this spring which hangs down the body of the spring balance. The object to be weighed is suspended from the hook and weight is indicated on the graduated scale.

What is the principle of spring balance?

The spring balance (also known as spring scale) is simply a spring fixed at one end with a hook to attach an object at the other. It works by Hooke’s Law, which states that the force needed to extend a spring is proportional to the distance that spring is extended from its rest position.

### What objects can be weight a spring balance?

Main uses of spring balances are to weigh heavy loads such as trucks, storage silos, and material carried on a conveyor belt . They are also common in science education as basic accelerators. They are used when the accuracy afforded by other types of scales can be sacrificed for simplicity, cheapness, and robustness.

### How does a spring balance work?

A balance spring, or hairspring, is a spring attached to the balance wheel in mechanical timepieces. It causes the balance wheel to oscillate with a resonant frequency when the timepiece is running, which controls the speed at which the wheels of the timepiece turn, thus the rate of movement of the hands.
