The difference between mass, weight and gravity

Mass is a measure of the translational inertia (inertial mass) and gravitational action (gravitational mass) of an object. The main unit of mass in the international system of units (SI) is kilogram (kg). Gravity is the force exerted by an object under the action of gravity field. Generally, it is the attraction of the earth to an object. Weight is the magnitude of the gravity force. Gravity is a non free vector (the direction is vertical and downward relative to the horizontal plane), But the weight is scalar (only size, no direction and no starting point), which is the difference between them. The force (including gravity or weight) is defined in Si by the translational inertia of Newton's second law (where the scale coefficient is dimensionless number 1), and the main unit is Newton. The symbol n, 1n = 1kg · M / s indicates the force that makes 1kg mass object obtain 1m / s acceleration, It's totally different. It's incorrect to use the unit of mass for weight. For example, "the weight of an object is 100 kg", which means "the weight of an object is equal to 100 kg force". The kilogram force (KGF) is the main unit of force in the engineering unit system, which means that the weight of a 1 kg mass object is affected by the gravity of the earth, In SI system, the main unit is mole, and the symbol is mol

The difference between mass and gravity
I know they are totally different, but I don't know how to distinguish them. Gravity refers to the force exerted by the earth's gravity on an object. Isn't that what we call the weight of this object in life? Is it because of gravity that an object has weight
What's the weight of this object? Does it mean its mass or gravity

You're right, but we can't study physics only from the earth! The unit of mass is the same. It's the same everywhere in the universe. For example, my mass is 60 kg, I'm 60 kg on the moon, and I'm 60 kg on Mars. But the accurate unit of gravity should be Newton, I'm on the earth

What's the difference between gravity and mass?

We should pay attention to the distinction between the two physical quantities of gravity and mass. We should not regard the weight of the object (i.e. the weight of the object) and the amount of material contained in the object (i.e. the mass) as the same thing, and confuse the two concepts

① An object with a mass of 1 kg weighs 9.8N
② The gravity of an object is directly proportional to its mass. The formula g = mg
[note]
① The direction of gravity is always vertical and downward. Note that the meaning of "vertical" is different from that of "vertical"
② The physical meaning of G is that an object with a mass of 1kg weighs 9.8N

What are the units of mass, weight and gravity?

Newton
Newton
The magnitude of gravity is called weight

What is the relationship between gravity, mass and weight? Are they all the same?
I can't understand these physics knowledge all the time. Ask the teacher. She even talks about it noisily, which makes me confused/

1 L is wrong. Mass refers to the amount of material contained in an object. To put it more popularly, it means how much weight we usually talk about. Gravity means that an object is affected by the gravity of the earth because it has mass. It is because the object has mass. There is universal gravitation between it and the earth. The earth is attractive to it. This attraction is

What does weight mean, mass or gravity

Physical weight refers to the magnitude of gravity
The "weight" in life refers to the mass in physics

The unit of m in the formula for calculating gravity
In the calculation of gravity g = mg, is the unit of M kg or G 0 *,

It's kg! International system of units!

The international unit of force Newton is defined as what force is a Newton?

The force required to make an object of one kilogram gain an acceleration of one meter per second is defined as 1 Newton

What is the concept of 1 Newton (1n) in mechanics?
What I want to ask is the relationship between one newton and one kilogram

It can make 1kg object produce 1m / S ^ 2 acceleration;
The gravity of a kilogram object is 9.8N, but it increases with latitude and decreases with altitude

What forces does junior high school mechanics include? Such as friction, power, gravity (including concepts in various fields)

Friction, the surface of objects in contact with each other, has relative motion, so there will be friction. The size and coefficient of friction are related to the tangential force. Gravity, needless to say, is actually a kind of universal gravitation. The buoyancy of liquid, the object immersed in liquid will be affected by the buoyancy of liquid. The size is equal to the density of liquid multiplied by G, and then multiplied by the immersed
