    You're not pointing down to throw, you're letting go at the same time)

    In fact, they do not land at the same time, because there is actually always air resistance, and the air resistance of large and small stones is different, so they do not land at the same time.

    But if in an ideal state, ignoring the air resistance, according to the law of free fall h= gt, the fall time t is only related to the falling height h, since the same height falls at the same time, then of course it lands at the same time.

    As for the law of free fall, you can check out the compulsory one or related extracurricular books in the first year of high school.

    Theoretically, two objects at the same position and at the same height are in free fall, they land on the ground at the same time. However, this may not be the case in practice, because the effect of frictional resistance, which is related to the surface parameters of the object, is taken into account. You add to this question, the question is not clear, because you are talking about throwing, not free fall, and the direction and velocity of the throw will directly determine the velocity of the object in the vertical direction in the initial state.

    If it is thrown horizontally, it does not matter whether the throwing speed of the two stones is the same or not, because the velocity component in the vertical direction is 0, they will land at the same time; If the direction is not the same, the velocity is not the same, it may or may not land at the same time, or it depends on the velocity component in the vertical direction; If one direction or velocity is the same, and the other is different, they will not land at the same time; If they are all consistent, they will land at the same time. I don't know if I understand you accurately.

    In a vacuum, there is no air resistance, and the acceleration of the object (a) = m (mass of the object) * g (acceleration due to gravity) m = g. When two objects of different masses are released at the same time, the time taken (t) = under the root number (2*h "height g>". Both h and g are the same, so t is the same.

    That is, a large stone and a small stone are thrown down together and land on the ground at the same time.

    Newton did this experiment at the Leaning Tower of Pisa, where two iron balls, one pound and one ten-pound, fell at the top of the tower at the same time, and landed on the ground at the same time. Ignoring the effect of air resistance, they are subjected to the same acceleration due to gravity, so the state of motion is the same. Not to mention the size of the stones, even if cotton and iron are in a vacuum, they are not affected by air resistance, they also land at the same time.

    Generally speaking, the test point of your question should be gravitational acceleration. Although it is not said, the premise should be to ignore air resistance. If that's the case...

    Then this question is landed at the same time. The reason is precisely because of the same gravitational pull. The acceleration due to gravity is all g.

    If they are not affected by other resistance, they have the same initial velocity, the same gravitational acceleration, and the same distance, so they fall at the same time.

    Unless there is a vacuum, objects of different weights do not hit the ground at the same time.

    In theory, it is possible to land at the same time without considering air resistance, provided that it falls from the same height at the same time, and the requirement is a free fall movement.

    Hasn't anyone ever experimented with gravitational acceleration in g, of course.

  10. Anonymous users2024-01-30

    Yes because the acceleration due to gravity is g

    According to Galileo's logic, he said that if air resistance is completely excluded, then all objects will fall equally fast. That's what he said, I'm not a scientist, I can't give a perfect answer, in his words, maybe it will give you some inspiration, (his words are taken from a high school physics textbook) Actually, I quite agree,,You are thinking about it.

    First of all, any object, in any place, its mass is the same, but the weight is different, that is, how many catties we usually weigh and see, this is because gravity is not the same, in time on the earth, the weight of the same object in different places is also a little different, the gravity of the equator and the poles is different, there are different, in addition, the weight of the same object on the earth and the moon is also different, the gravity of the moon is one-sixth of the earth, that is to say, a figured object, If you use the scale, it is 6 catties on the earth, and only 1 catty on the moon.

    The weight varies from place to place. The gravitational force of the same object is not the same at different latitudes of the earth, and the gravitational force is provided by one component of gravitational force, and the other component provides the centripetal force of the object and the earth moving in a circular motion. The higher the latitude, the less centripetal force is required, so the more parts are divided into gravity, so as the latitude gets higher, the gravity also increases, and the maximum value of gravity appears at the poles.

    The Moon weighs less than the Earth.

    The weight of a person varies in different parts of the earth. The mass of human beings will not change, but the weight of human beings is different in different places, because the radius of the earth is different, and the linear velocity of rotation in various parts of the earth is different. Even for a standard sphere, if the centripetal force mentioned below is taken into account, the weight of people will vary depending on the latitude.

    Strictly speaking, gravity does not point to the center of the earth, and it is generally said to be vertically downward.

    Because people will rotate with the earth and have a circular motion, there will be a centripetal force, the centripetal force points to the earth's axis, but the centripetal force is very small and small, generally negligible, you can try to use the centripetal force formula to roughly find it, but if the emphasis is on the concept, it should still be taken into account. The combined force of gravity and this centripetal force is the gravitational force, and this force is directed towards the center of the earth.

    Not the same.

    The weight of an object is related to the gravitational force experienced by the object, and on different planets, the gravitational acceleration is different, and the weight of the object is of course different. Even on the same planet (e.g., Earth), gravitational acceleration varies with position and altitude.

    In addition, weight and mass are not the same concept. The mass of an object is the amount of matter that the object contains. This does not vary with position, but with speed (as close to the speed of light).

    In different places, the mass of the object is the same, but the weight is not necessarily the same, different latitudes on the earth, the gravitational acceleration g is different, the weight g is equal to mg, m is the same, and g is slightly different in different places, if the same object is brought to the moon, the mass m is unchanged, and the gravitational acceleration on the moon is about one-sixth of the earth, and the gravity of the object with the same mass is only about one-sixth of the earth.

    The same kind of object is placed in different places. The quality of the scale is strictly not the same. , it depends on the accuracy and requirements.

    Theoretically, the gravitational coefficient is different in different parts of the earth. Larger on different planets.

  17. Anonymous users2024-01-23

    No, because in some places the gravitational pull of the earth is large, the mass of the object will be greater.

    Does the weight of the object be the same in different places? The weight of the object varies from site to site, for example, cotton, which weighs differently on the ground than in the water. And so on, there are many objects that are not the same weight.

    No, in some places, the size of gravity is different, and the weight is different.

    How does it work to lower two iron balls down different slopes only to land at the same time?

  25. Anonymous users2024-01-15

    It falls at the same time because the gravitational acceleration is the same. The reason for emphasizing a vacuum environment is because there are many factors that go into a non-vacuum environment, usually referring to the resistance of the air. The pressure of the opposite air on an object with the same velocity is equal, and the resistance is mainly determined by the size of the area of force according to the pressure * area of force.

    Therefore, it can be inferred that the force area of the ball should be larger, and the resistance should be larger, and it will land backwards. However, the difference between the forces of the two spheres is very small relative to their gravity, and the height of the towers is limited, so this difference is not visible.

    Aristotle believed that heavy objects fall quickly, while the gravity of the two pieces of paper used by Xiao Gang is the same, and no matter what shape it is, the moment of landing should be the same;

    In order to test Galileo's point that objects of different weights fall at the same speed and at the same speed, the experiment must be carried out using the same air resistance at all times or in a vacuum

    Therefore, the answer is: 1) the paper ball and the paper piece should fall to the ground at the same time;

    2) The surface area of the paper is subject to different air resistance
