Regarding the quality of objects in physics, I am very eager for someone who knows about it to help

1: Is it true that the higher the mass of the object, the faster it will fall when we throw it down than the lighter one? Why is that? The answer, please search for the free fall experiment yourself, don't ask others, see for yourself!

2: Elementary: Mass indicates how much matter an object contains.

Mass is a basic property of an object, which has nothing to do with changes in the state, shape, temperature, and position of the object in space.

The amount of substance contained in different objects is not necessarily the same. The amount of matter contained in an object is called the mass of the object. The unit is different from the weight, although it is measured in kg, but the mass is a little smaller relative to the weight.

Quality is a qualitative attribute and a substantiated quantity, and energy is a quantified quantity. Energy and mass can be converted into each other, but they are different quantities.

Mass can be understood as the amount of quality (quantity, transformable energy).

The mass is large, and the object contains a lot of matter; The mass is small, and the object contains less substance.

High School: Mass, is a physical quantity that describes the inertia of an object.

Mass is the only factor that determines how easily an object's state of motion changes when it is subjected to force.

Now the instruments that manage the quality are stored in Paris. Mass in Physics The amount of matter that an object contains is called mass. Mass does not change with the shape of the object and the position in space and is one of the fundamental properties of matter, which is usually denoted by m.

The unit of mass in the International System of Units is kilograms, or kilograms.

The first question is that this is the case on Earth, because buoyancy affects acceleration, initial velocity is the main factor that determines the decline, and air resistance is related to velocity.

Mass on Earth is equal to weight, but placed on the Moon, the mass does not change, but the weight changes, weight is related to the acceleration of gravity, that is, g, mass is its property and does not change.

Galileo's experiment, which I heard was done on the Leaning Tower of Pisa, was to put a feather and an iron ball together, and the result fell to the ground at the same time, in fact, this can only exist in the absence of air.

According to Galileo's experiment with the Leaning Tower of Pisa (which was later confirmed to have been done by one of Galileo's students, but it doesn't matter), mass has nothing to do with acceleration. However, recent accurate measurements by scientists have found that even in a vacuum (without resistance), the acceleration of objects with different masses is different, which has led to the conclusion that there is no fifth fundamental force in the universe (the other four are checked by themselves...).

Mass is divided into inertial mass and gravitational mass (although they are exactly the same size). Mass cannot be directly represented, but can only be characterized in the form of other forces. For example, the gravitational force divided by the gravitational acceleration is the gravitational mass. Please refer to the details here.
