The difference in mass and weight, is the mass and weight the same

From a physical point of view, weight refers to the force of gravity. Because there is no such thing as weight in physics, it is a living representation of gravity. For example, when we buy something, the merchant will weigh us, but in fact, this process is due to the gravity of the object at work.

Gravity is a force of attraction of the earth to objects. Weigh an object in a spaceship, and you will find that an object that is very heavy on the earth has no weight (in real time, there is no gravity) on the spaceship (which is weightless at this time).

Mass refers to the amount of matter that an object still has, for example, how many small particles of wood a table contains, and it will always contain that much. Doesn't change with location. Weight, i.e., gravity, changes with position.

Their connection: the unit of weight in life is the kilogram, and the unit of mass in physics is also the kilogram. This is because on Earth, mass and gravity maintain a relationship, i.e., g=mg, while g on the earth is basically constant.

The definition is different. Mass is a physical property possessed by an object, and in some cases, it can be used to measure the magnitude of the inertia of an object; In some cases, it can also be used to measure the ability of an object and other objects to attract each other. Whereas, weight indicates the magnitude of the gravitational force experienced by an object and is the value of a force.

That is, the weight represents the value of the resultant force of the earth's gravitational force on the object and the inertial centrifugal force acting on the object due to the rotation of the earth. The weight of an object is equal to the product of the mass of that object and the value of the acceleration due to gravity.

Mass refers to the mass of an object, which is a property that does not change with the environment.

Weight is created because an object with mass receives the gravitational pull of the Earth or other stars, and the gravitational force changes, and so does the weight.

This weight is fixed, the unit is kilograms, the same object is the same on Earth and on the Moon, the mass is related to g, and then changes.

Mass: The amount of matter contained in an object, the mass is equal to the density multiplied by the volume.

Weight: The gravitational force experienced by an object, g mg, m is the mass, g is a fixed value indicating the ratio of weight to mass, in different regions, g value is different.

In general, the quality has nothing to do with the outside world, and the weight has to do with the geographical location.

For example, an astronaut floats in the sky, and his mass is the same as on Earth, but his weight is

Mass and weight are not the same, they are two physical quantities. The reflection content of mass and weight is different, the quantity is different, the measurement method is different, and the unit is different.

Mass and weight are not the same, they are two physical quantities.

First, the content of the reflection is different.

1. Mass is a measure of the inertia of an object, and it is a property inherent in any object.

2. Weight reflects the magnitude of the gravitational force on the object, which is caused by the attraction of the earth.

Second, the amount is different.

1. Quality is a scalar quantity. Mass is only numerical value.

2. Weight is a vector, and weight refers to the downward perpendicular ground.

Third, the measurement method is different.

1. The quality is measured with a balance.

2. The weight is measured with a spring scale.

Fourth, the units are different.

1. The unit of mass and weight is the kilogram in the International System of Units.

2. The unit of weight is newtons. In practice, the unit of weight is usually kilogram-force or gram-force.

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 kilogram is called 1 kilogram weight when it is subjected to an external force of 1 Newton.

Mass and weight are two concepts in physics that share some similarities but also have significant differences. Mass is the inertia possessed by an object, i.e., the property of the object when it is not subjected to force, and is a scalar dimension in kilograms. Whereas, weight is the force produced by the gravitational pull of the earth on an object and is a vector dimension in Newtons.

The relationship between mass and weight can be explained by the law of gravitation. The magnitude of the gravitational pull of the earth on the object depends on the mass of the object and the mass of the earth, whereas the formula is f=g*m1*m2 r 2. where f is the gravitational force experienced by the object, g is the gravitational constant, m1 and m2 are the masses of the earth and the object, respectively, and r is the distance between the earth and the object.

Therefore, the weight of an object can be measured by its mass and the gravitational acceleration of its position.

Although mass and weight are different concepts, there is a certain connection between them. In the vicinity of the Earth's surface, the imaginary weight of an object can be approximately equal to the product of its mass and the acceleration of the Earth's focal gravity. Therefore, when we talk about the weight of an object in our daily life, we are actually referring to the embodiment of its mass on the earth's surface.

In conclusion, mass and weight, although very different, are very fundamental concepts in physics. Understanding the relationship between them can help us better understand other concepts in physics, such as force, acceleration, motion, and many more.
