What is the main use of 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.

What is a spring balance how does it work?

Spring balance is used to measure the weight of the object. When a load is hung on the spring, it stretches and the spring’s extension is proportional to the weight of the object. The working principle of the spring balance is Hooke’s law which is F=−kx. Was this answer helpful?

How is spring balance used to measure weight?

Why physical balance is used?

Basically, a physical balance is simply a weight measuring instrument. It is used to measure the weight of any unknown object with the help of the other object with known weight.

How do you read a spring balance?

What is the reading of the spring balance on the smooth surface?

Answer: reading of spring balance indicates that the force of friction has decreased.

What is the use of spring balance Class 8?

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 principle is used in a newton spring balance?

The principle used in newton spring balance is the extension of the spring is directly proportional to the force pulling.

What is range of spring balance?

Consider a spring balance whose range is 0-25kg. In its scale, you can see that the 1kg is divided into 10 equal parts. Therefore, the least value it can measure is 100g which can be found out by, Measurement =1kg.

What is spring balance short answer?

Spring balance is a device used to measure the weight of small bodies. It consists of a spring to hang the weights. As the weights are hung to the spring it stretches the the pointer indicates the weight hung or the force applied on the spring.

What is spring balance Class 9?

Spring balance is a device used for measuring force on the object. It has a spring attached to a hook. When we attach the hook to the weight, the spring extends and the pointer shows us the Force in Newtons.

How can we use spring balance to measure the weight of an object class 8?

Answer: Measure weight or force by hanging objects from the spring scale hook. Measure weight or force by hanging objects from the spring scale hook. Measure loose material, such as sand, by pouring it into a plastic bag and hanging the bag from the hook.

What is spring balance write its construction and working with the help of Diagram 4?

It consists of 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. Therefore, the scale markings on the spring balance are equally spaced.

What causes friction Class 8?

Friction is caused by the interlocking of irregularities in the surface of two objects which are in contact with each other. To move one object over the other ,we have to apply a force to overcome interlocking of the irregularities in their surfaces.

What causes friction?

Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.

What is spring balance 8 friction?

Spring balance is a device used for measuring the force acting on an object. It consists of a coiled spring which gets stretched when a force is applied to it. Stretching of the spring is measured by a pointer moving on a graduated scale. The reading on the scale gives the magnitude of the force.

What is friction Byjus?

Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other. Friction provides traction that is needed to walk without slipping.

What is friction notes?

It is a force which opposes motion of one object over another object in contact with it. In easy language,it is a force which makes moving object stop.

What is sliding friction?

Definition of sliding friction

: the friction between two bodies that are in sliding contact. — called also kinetic friction.

What is impulsive force?

An impulsive force is a force which acts on an object for a short period of time. In a collision that results in a change in the velocity or momentum of one or more the objects involved in the collision, an impulsive force is primarily produced.

What is sound 8th class?

Sound is a form of energy and it comes from vibrations. These vibrations create sound waves which move through mediums such as air and water before reaching our ears.
