What is the relationship between mass and weight?

Mass is the amount of matter in an object, gravity is the force that the earth attracts to an object, and weight is the amount of gravity experienced by an object. The unit of gravity is Newton, and the unit of mass is kilogram. Metal objects and sand have the same mass, and they have the same weight under certain conditions of gravitational acceleration.

Quality is the same weight.

As for what exactly mass is, no scientist in the world has yet been able to say clearly.

Mass-encyclopedia: "The quantity of matter contained in an object is called mass, which is a physical quantity that measures the gravitational potential energy and kinetic energy of an object at the same place". We can see from the definition of mass, the physical quantity of the gravitational potential energy of an object at the same place, that mass is weight 1.

In the gravitational formula g=mg, since g is a variable and m is an invariant, it can also be seen that the mass m is the invariant weight that is not affected by g.

We can see from the fact that mass is the constant weight, mass is weight, weight is gravity, gravity is gravity, mass is gravity, and gravity is magnetism.

The acceleration g of gravity is directly proportional to the strength of the magnetic field. g is the largest in the polar region and the smallest in the equatorial region, because the magnetic field strength is greatest in the polar regions. The magnetic field strength at the equator on the Earth's surface is about Gaussian (, while the magnetic field strength of the geomagnetic north pole is Gauss, and the magnetic field strength of the geomagnetic south pole is Gauss2, so the weight of the same object at the equator is lighter than that of the poles.

The acceleration of gravity g and the centrifugal force are in opposite directions. The centrifugal force is greatest at the Earth's equator and the poles are 0, so the weight of the same object at the equator is lighter than at the poles.

A man on the moon weighs one-sixth as much as a man on Earth. This is because the magnetic field strength on the Moon is 1 10 -9 - 5 10 -9 (t) 3, which is smaller than the Earth's magnetic field strength, that is, g is smaller, so the weight g = mg is light.

We can see from the fact that mass is the constant weight, and the reason why people put forward the word mass is for the convenience of calculation, because the weight varies from place to place, and g to g. It's like the speed of a 100-meter athlete is affected by the wind speed. The speed with wind and the speed without wind are the speed (weight) of the 100-meter athlete, but the speed without wind is the same as the real athlete's 100-meter speed (mass).

This is like if we have to specify a uniform wind speed (no wind speed (g)) in a 100-meter race in order to compare the speed of a 100-meter runner.

It's just that we take the speed of the 100-meter athlete under the influence of wind speed as the speed (weight) of the 100-meter athlete, and the speed of the 100-meter athlete without the influence of the wind speed as the real speed (mass) of the 100-meter athlete. Therefore, the true speed (mass) of the 100-meter athlete is also the speed (weight) of the 100-meter athlete, and the true speed (mass) of the 100-meter athlete is the speed (weight) of the constant 100-meter athlete.

Mass is defined as how much mass an object contains, but this definition has been questioned a lot due to the ambiguity of the definition of matter itself. A more concise and accepted way to define quality is to define it by inertia. The inertia of an object can be defined as the force that causes it to accelerate, move, or hold motion until its motion is stopped by another force.

A special property of mass is that it is constant no matter where it is in space. Gravity tells us that two objects are attracted to each other, and the force of attraction between them is directly proportional to the mass, but the force itself has no effect on the mass. A 60 kg brick is also 60 kg on Earth, on Mars or Venus or some unknown far corner of the universe.

In the same place, the gravitational force of a given mass m is mg (g is the gravitational acceleration in the same place), and if the gravitational force on the left and right sides of the balance is equal, the balance is balanced, which means that the mass on the left and right sides of the balance is the same.

The balance is a very old tool. It was called in ancient China"Balance", which means stick. The ** below shows the scales and their weights made during the Warring States period in ancient China.

The gravitational acceleration of an object is different in different places, in other words, the same mass in different places, such as the equator, or the south pole, will measure different weights. If we extend the concept of weight to the Moon or Mars, then an object of the same weight will be less weighted when it is transported from the Earth to the Moon or Mars. Mass determines how easily an object changes its state of motion when it is subjected to force, so mass is a physical quantity that describes the inertia of matter.

In Einstein's mass-energy equation e=mc, it is easy to see that mass and energy are equivalent but it does not mean that mass is energy, and there is as much energy as there is mass in an object.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The unit of mass is kilograms, the unit of weight is ox, the mass of an item is its property, the mass does not change with the change of gravitational acceleration, however the weight changes with the change of gravitational acceleration and does not belong to the inherent nature of the object.

The relationship between mass and weight is g=mg, and mass is a property of an object, and mass does not change weight with the shape of the object, so I think the relationship between mass and weight is very close.

Mass is the amount of matter contained in an object, weight is due to the gravitational force experienced by the object, and weight is equal to mass multiplied by gravitational acceleration.

Weight is equal to mass multiplied by density, and the relationship between the two can be converted to each other according to density, and the relationship is relatively close.

Quality is the amount of matter contained in an object, and the component is the weight produced by the gravitational force of the object equal to virtue multiplied by the acceleration of gravity.

It's not the same thing, mass is a measure of the amount of matter, the unit is "kilogram (kg)", and the mass of an object is the same no matter if it is placed in **; The weight is related to the strength of the gravitational field, and the unit is "Newton (n)", and the weight of the same object on the Earth and the Moon is not the same.

Of course it's not the same thing. Mass is a physical quantity that measures the translational inertia of an object, and weight is a measure of the magnitude of an object subjected to gravity, which is a basic property of an object. Mass and weight are measured differently, with mass measured on a balance and weight measured on a spring scale.

Mass: Indicates the amount of matter that an object contains. Mass is a basic property of an object, which has nothing to do with the change of the state, shape, temperature, and spatial position of the object, it is a physical property of the object, and it is a measure of the quantity of matter, and it is a positive scalar quantity.

Weight: The amount of gravitational force exerted on an object near the Earth's surface. Weight is the amount of downward force that an object has under the action of gravity, pointing towards the center of the earth, also known as gravity.

The relationship between weight (g) and mass (m) is g = mg (where g is the acceleration of gravity and the value is .

Mass is a physical quantity that measures the inertia of an object, and is the only factor that determines the difficulty of the change of the motion state of the object when it is subjected to force, so mass is a physical quantity that describes the inertia of matter.

Mass is one of the fundamental dimensions in physics, with the symbol m. In the International System of Units, the basic unit of mass is the kilogram (symbol kg). Balances are a common tool for measuring quality in the laboratory.

Weight is a measure of the force of an object after being subjected to gravitational force, and weight and mass are different. The unit is kilogram weight. Under the gravitational pull of the Earth, weight and mass are equivalent, but the units of measurement are different.

The weight of a substance with a mass of 1 kg is called 1 kg weight when it is subjected to an external force of 1 Newton.

Mass and weight are two important concepts in physics, and they also have great applications in our daily lives. Mass refers to the inertia possessed by an object, i.e., the ability of an object to resist changing its state, while weight refers to the amount of gravitational pull on the earth experienced by the buried bonding object. Although mass and weight are two different concepts, there is also a close relationship between them.

First of all, the relationship between mass and weight can be expressed by physical formulas. According to Newton's second law, the force experienced by an object is equal to its mass multiplied by acceleration, i.e., f = ma. Whereas, gravitational acceleration g refers to the acceleration on the surface produced by the gravitational pull of the earth on the object, so the gravitational force experienced by the object is equal to its mass multiplied by the acceleration due to gravity, i.e., w=mg.

From this, it can be seen that the weight of an object is directly proportional to its mass, i.e., the greater the mass, the greater the weight.

Secondly, mass and weight are also closely related, as they are both fundamental properties of objects. The mass of an object determines its inertia and state of motion, while the weight determines the force on the earth. In practical applications, mass and weight are also often used to indicate the size and importance of an object.

For example, we often use the word "heavyweight" to describe the importance of a person or event, while the word "lightweight" means the opposite.

Finally, we also need to note that mass and weight are two different concepts and should not be used confusingly. When calculating the weight of a machine, we need to consider its mass, not its volume or size. At the same time, when conducting scientific research, we also need to accurately distinguish between mass and weight in order to draw correct data and conclusions.

In conclusion, mass and weight are two important concepts in physics, and they have a close relationship with each other. Mass determines the inertia and state of motion of the object, while weight determines the force of the object on the earth. Understanding the relationship between mass and weight can help us better understand the principles of physics, while also allowing us to use these concepts more accurately in our daily lives.

The relationship between weight (g) and mass (m): g=mg (where g is the acceleration of gravity, and the value is explained in detail below:

The concept of mass: The amount of matter contained in an object is called mass.

Physical quantity symbol of mass: m;

The unit of mass: the International System of Units of mass: kilogram (kg), also known as kilogram (kg);

Characteristics of mass: Mass is a property of the object itself; The mass does not change with the shape, state, position, temperature, etc. of the object (i.e., the magnitude of the mass has nothing to do with the shape, state, position, temperature, etc. of the object);

The concept of weight: Weight is another term for gravity in everyday life. The force exerted on an object near the ground due to the attraction of the earth is called gravity, also known as weight.

Physical quantity symbol of weight: g;

Units of weight: SI units of weight: Newton (n);

Characteristics of weight: Weight, i.e., gravity, is the force on an object due to the attraction of the earth. For a given object at a given position, the gravitational force on the object has nothing to do with the state of motion and velocity it is in. The weight of the object changes with the acceleration due to gravity.
