What is the least count of the spring balance shown below?
Therefore, the minimum value it can measure is one hundred grams, which can be measured as follows: Measurement = 1 kg Total Number of divisions = 10 Least count= (1/10) = 0.1kg (or 100g) Hence 100g is the least count of this instrument.
What do you mean by least count of spring balance?
Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument. For example, Take a spring balance whose range is 0-25kg. In this scale, you can see that the 1kg is divided into 10 equal parts.
How does a spring balance look like?
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 is a Newton spring balance?
A spring balance (or newton meter) is a type of weighing scale. They are commonly used to measure the force exerted on an object. This force is usually measured in Newtons and is essentially the weight of an object. The weight of an object is a measurement of its mass x gravity (W=mg).
What will happen if you keep on adding more padlocks to the spring balance?
3. Predict what will happen if you keep on adding more padlocks to the sprig balance. (The more padlocks hanged, the lower the spring will be pulled down.) 4.
What is a spring balance Class 8?
Class 8 Question Spring balance is a device used to measure the weight of small bodies. 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 is the working principle of spring balance?
principle of Hooke’s law
What is the meaning of spring scale?
: a scale in which the weight indications depend upon the change of shape or of dimensions of an elastic body or system of such bodies.
Why do we use a pan balance?
The pan balance is a useful tool to check the relative weights of any two cubes.
What is a top pan balance?
A top pan or top loading balance is an instrument used to weigh solid materials when perfectly accurate measurements aren’t necessary. Most top pans have 0.1-gram to 0.001-gram precision and weighing capacities of 500 grams and above.
Is balance a weight?
Technically, a balance compares weight rather than mass, but, in a given gravitational field (such as Earth’s gravity), the weight of an object is proportional to its mass, so the standard masses used with balances are usually labeled in units of mass (e.g. g or kg).
What is a balanced weight?
n. (General Engineering) engineering a weight used in machines to counterbalance a part, as of a crankshaft. Also called: bobweight.
What are the four kinds of balances?
There are four main types of balance: symmetrical, asymmetrical, radial, and crystallographic.
