"Why did the apple fall":

1, gravitation is a theory put forward by Newton in17th century. It means that in nature, all objects will produce gravity, and the magnitude of this force is related to the mass and distance of the objects. Therefore, when the distance between the earth and the apple becomes smaller, this attraction will increase, and the apple will be attracted downward by the earth and eventually fall to the ground.

2. Gravity is not the only influencing factor. Other factors such as wind, the quality and structure of the fruit itself will also affect the process of apple falling. Because the wind will produce resistance to apples, which will slow down the landing speed of apples; The quality and structure of apple itself will also affect its falling speed and landing mode.

3. The question "Why did Apple fall" seems simple, but it actually involves many factors. But in any case, the root cause of the fall is gravity. This process is not only the apple falling, but also an important basic concept in physics, which guides people to explore more profound natural phenomena.
