The Mass Of A Body Depends On

several factors, such as its composition, density and volume. Mass is a fundamental physical property that determines the amount of matter a body contains and its influence on gravity.

What is mass and an example?

Definition of Mass

Mass is a physical quantity that represents the amount of matter contained in a body. Its etymological origin is found in the Latin word “massa”, which in turn comes from the Greek “madza”, which referred to a cake made with flour.

Within the International System, the unit of measurement for mass is the kilogram (kg).

In the context of food, dough also refers to the mixture of yeast, water and flour used to make bread and other food products.

How can you determine the mass?


Matter can be classified into physical and chemical changes. It can also be measured using fundamental and derived quantities. To measure different properties of matter, measuring instruments are used such as those that measure length, mass, temperature, time and volume. In addition, there are indirect measures that allow us to obtain information on the matter. The states of aggregation of matter are another important aspect to take into account. Matter is made up of atoms and can be classified in different ways. Finally, a final task is presented which consists of using instruments to measure the mass of different objects.

What determines the mass of an object?

Mass is a fundamental quantity in determining the amount of substance. In this context, the properties of inertia and gravity are defined. Inertia implies that an external force is needed to change the direction or speed of movement of an object. Gravity is the result of the attraction between the masses of bodies. The unit of measurement for mass is the kilogram (kg).

Determination of mass is done through weighing. A balance is used to determine the weight of a substance, which is proportional to the mass. The unit of measurement for weight is the Newton (N). In common usage, this relationship is often neglected and the term weight is used as a synonym for mass.

What does mass have to do with gravity?

The force of gravity is an important concept in physics. The mass of a body refers to the amount of matter it contains, while the weight is the force with which the planet attracts that body. Weight is calculated by multiplying mass by the intensity of gravity, which can vary in different locations. The balance is used to measure masses, since on both sides of the pan there is the same value of gravity. On the other hand, the dynamometer is used to measure forces, but if it is used to measure weights, it will give different values ​​depending on the height of the place or planet where we are. In short, mass always has the same value, while weight depends on the intensity of gravity.

What is the mass of a body?

The Royal Spanish Academy (RAE) is the association of academies of the Spanish language in charge of publishing the Dictionary of the Spanish Language in its Tercentenary edition. In its 2022 update, the RAE offers resources such as UNIDRAE, linguistic consultations, grammar, spelling, Corpes XXI, DHLE, archive, bulletins, among others. Thanks to its commitment to culture, it is possible to search for words in the twenty-third edition of the dictionary. One of the terms that can be searched is “dough”, which has multiple meanings such as the physical magnitude that expresses the amount of matter in a body, a thick and consistent mixture, the mixture of flour and water to make bread, among others. In addition, there are other related expressions such as “atomic mass”, “critical mass”, “wage mass”, among others. Also mentioned is the action of “giving mass” in the electrical field and the expression “in mass” to refer to something that is done together. In summary, the RAE offers a wide range of linguistic resources and consultations to enrich your knowledge of the Spanish language.

What relationship exists between the mass?

The buoyancy of an object in water depends on its density. If we compare a block of wood and a block of iron of the same mass, the block of wood will float while the block of iron will sink. This is because the density of wood is lower than that of water, while the density of iron is higher.

Density is a physical property that relates the mass of a body to the volume it occupies. It is represented by “d” and is expressed mathematically as mass divided by volume. It is measured in units of mass divided by units of volume, such as kilogram per cubic meter (Kg/m3) in the international system.

Objects less dense than water float in water, while more dense objects sink. This means that for the same substance in the same state of aggregation, the density is constant and invariable. For example, the density of water is 1 Kg/m3, which means that in 1 liter of water there is a mass of 1 Kg. If we double the mass, it will occupy a volume of 2 liters.

Below is a table with density values ​​in Kg/m3 for some common substances:

– Iron: 7500
– Marble: 2700
– Glass: 2500
– Olive oil: 910
– Air: 13

What is mass and weight?

The confusion between mass and weight continues to be a topic of debate. Mass refers to the amount of matter in an object and is measured in kilograms (kg), while weight is the force with which gravity attracts matter and is measured in newtons (N). Weight may vary depending on location. On Earth, weight is greater at the poles and at sea level than at the equator or at the top of a mountain. On other planets like Mars or the Moon, the weight is less due to the lower force of gravity. However, mass is conserved and neither created nor destroyed. Therefore, the incorrect information from La Voz on April 7, based on the Reuters agency, stating that the mass volatilizes in space or is reduced on other planets, is erroneous. The mass of an object remains the same, regardless of its location. Contributing to this confusion is the lack of the verb “masar” to measure masses, in contrast to the verb “weigh” to measure weights. Professor Guillermo Rojo is expected to propose the inclusion of the verb “masar” in the dictionary to clarify this distinction. In the meantime, the term “weigh” will continue to be used to measure masses in kg and also to measure forces in N, ensuring confusion between mass and weight for life.

How is the mass of a body related to its weight?

The teacher’s area addresses the topic of mass measurement in the primary school Mathematics curriculum. Although space and time present uniformity, matter is diverse and occurs in different forms. However, we can find something that all objects that are matter share. The balance has allowed man to measure the amount of matter over time. Weight, on the other hand, is measured with a device called a dynamometer and is the measure of the attraction that the mass of the Earth exerts on a body. Difficulties in measuring mass include the need to measure large masses indirectly and the relationship between mass and volume, which is expressed as density. In the student’s mind, the concepts of mass and weight are often linked, but it is important to understand the difference between them. In Spain, most teachers prefer the term “mass” instead of “weight”. The program addresses the construction of a balance, the conservation of mass and its relationship with volume, knowledge of the mass standard, how to measure mass using different types of balances and other procedures, calculation with gram multiples and submultiples , the use of decimal numbers and fractions, and the elementary statistical treatment of mass measurements. The methodology and didactics of the program are based on a globalized presentation that involves interactive activities and the practice of exercises with solutions. Simulated materials are used to facilitate learning and develop attitudes such as curiosity, sensitivity towards precision, recognition of the importance of clarity of exposition and the feeling of learning in an attractive way. In summary, the program seeks to prepare the student to understand and apply dough-related concepts effectively.


The mass of an object is determined by the amount of matter it contains. Mass and weight are related, since weight is the force of gravity acting on an object and depends on its mass. Mass can be determined by measuring the force it exerts on a scale. Mass is a fundamental property of matter and can be exemplified by an object like an apple. Mass and gravity are related since gravity is the force that attracts objects towards the center of the Earth and depends on their mass. The relationship between mass and gravity is directly proportional, the greater the mass, the greater the force of gravity acting on the object.
