Science is a big knowledge umbrella that comprises of numerous research areas. People pick a filed and then gather more information on it and complete the research work. The learning process involves both theoretical concepts, formulae and calculations.

Consider that you wish to carry out how the energy is converted from potential to kinetic for a particle. This kind of research work is done at both academic and professional levels. In other words, both scientists and students work on this topic.

Calculations can be hectic and doing them manually can actually slow down the research. However, technology has provided a solution for all kinds of problems. You can use online calculators and get accurate results quickly. This would actually speed up the overall fact finding process.

If you search on Google, there are countless websites offering online calculators and one of them is Mera Calculator**.**

This website offers online calculation tools for different categories including the ones for scientific calculations. If you are dealing with numerical tools related to potential energy, force, sound wavelength and other related areas. However, before that, you need to know which tools would come in handy for you.

**Key calculators for scientific research work**

Various types of calculators are used by researchers depending on the requirements they have. Let us have a look at some of them.

**1. ****Avogadro’s Number Calculator**

This tool helps people who are related to chemistry and carrying out research work in the area of chemistry. In literal terms, Avogadro’s number defines the number of molecules in one mole of any substance. It has a default value of 6 X 10^{23. }If the parameters change, the corresponding value will change as well.

This tool incorporates four individual parameters

**M = Average atomic mass,****Z = Number of atoms within the crystal unit cell,****D = Density,****V = Volume**

The formula used by this tool is given as follows

N = (Z x M) / (D x V)

Chemical scientists who deal with molecules and their properties find this tool immensely helpful. It reduces the effort that these experts have to invest for completing the calculation tasks. Incorporating these four parameters and determining the correct results manually is quite tough. This is because research professionals have to concentrate more on interpretation of outputs. Experts who work on molecules and their properties do use this tool effectively.

**2. ****Force Calculator**

In accordance with Newton’s second law of motion, the force required to move an object is the product of the mass it has and the acceleration required. This law is a part of the physics as well as kinematics disciplines. Through this calculator, the required force can be calculated correctly and in a short while.

The formula is given as

F = m*a

Where

F = Force of Object

M = Mass of Object

A = Acceleration.

Suppose that an object has a mass of 10kg and the acceleration needed is 15m/s^{2}. In order to determine the force required, the following calculation will be completed.

F = 10*15

**Force = 150 N ( Newton’s)**

This kind of research is performed a lot by experts working in the automobile industry. They have to determine the force that the engine would exert to accelerate the mass of the car to the required limit. Through these calculators, Force values can be determined accurately without any hassle. The common scenario of using this tool is to determine the force on a particle that travels in two dimension.

**3. ****Work Calculator**

In scientific terms, the definition of work is very different from what we apply in our daily lives. It is defined as the product of force applied on an object and the distance that it covers. For instance, consist that you pick a stone and throw it till a distance of 100 meters with a force of 50N. Therefore, the work done on it will be defined as.

Work = Force X distance, when you insert the values given above, the following result will be attained.

Work = 100 X 50

**Work = 500 Joules**

- In literal terms, work is defined as the energy that is transferred to an object. This is the reason why “work” and “energy” both use Joules as the unit. This tool is handy for people working in the fields of core mechanics and object physics. These fields relate to the motion of objects. Most calculators falling in this category are free and can be accessed online with ease.

**4. ****Density Calculator**

Some research experts work on object properties and study a wide range including weight, appearance and density. In literal terms, density is defined as the ratio of mass and volume. Thus, the formula is given as.

**Density = Mass / Volume**

Consider that the volume of a substance is 10 m^{3} and mass is 100 g. Hence, density is given as ‘

D = 100 / 10

**D = 10 g / m ^{3}**

For research experts and scientists working on the area of density, this tool is a necessity. The reason being that they have to perform several calculations and cannot afford to spend a lot of time for this purpose. In addition to that, mistakes can ruin everything for them. Thus, using a good online density calculator is the best way out.

**Summing it Up**

For research experts and people working in the science sector, online calculators are quite important. The reason being that correct calculated results are essential to determine results and execute analysis.

We can take the example of a physics specialist working on the inertia of different objects. To perform comparisons, he would have to check the force applied on every object type. These busy professionals cannot afford to spend several hours on inserting values and performing detailed steps.

The important thing for them is getting to the desired results. Thus, there is no point in adopting a lengthy procedure to get to the outputs.
