Why do apples fall and why do apples fall from trees

The real reason for the falling object from the sky is the attraction of the center of the earth. Since the Earth is an object with a large volume and mass, the volume and mass of an apple are negligible compared to the Earth, equivalent to a particle. Because of gravity, the apple falls towards the center of the earth.

As for how to calculate the resistance it is subjected to, first of all, we need to figure out where the drag is generated, for the specific problem of the apple landing, its drag comes from the gravitational pull of other objects on the apple, such as: airplanes in the sky, animals on the ground, and even celestial bodies in outer space, etc., but these are very small compared to the gravitational force of the earth, and they can be ignored. But there is one case that excludes:

The force generated by the movement of the air flow on the apple, this force can change the trajectory of the apple as it falls, but it should be counted in the apple's resistance. So the drag force and gravity are not equal.

This problem was discovered by Newton and is called gravity.

In physics, Newton (symbol: N) was an army si unit, named after Sir Isaac Newton following his work as a classical mechanic. It was adopted by the Plenary Meeting on Weights and Measures (CGPM) in 1960.

It is defined as the force must be accelerated by one kilogram in large quantities at a rate of one meter per second.

Newton is the unit of si obtained, consisting of kilogram m s-2 in the si base unit.

Since the weight is an army acting between two objects due to gravity, Newton is also a unit of weight. A kilogram mass around the earth's surface has a weight of about Newton, although this number varies by a few hundredths of tenths on the earth's surface. Conversely, an object is weighed roughly one Newton in a mass of -1 kilogram (gram).

Quite fittingly, based on the story of Newton's discovery in gravity, which is about a small apple in abundance.

Why do ripe apples fall down? Is the Earth drawing it? Yes, it's the attraction of the earth! When the apples are ripe and fall downward, the stones thrown into the air will also fall downward, all because the earth is attracting them. Everything on the ground is attracted to the earth.

Back in. More than 300 years ago, physicist Isaac Newton discovered the law of universal gravitation. That is, the attraction of all substances to each other is related to the mass volume of the object.

Therefore, the moon also has a gravitational pull, but its gravitational force is 1/6 of that of the earth, and throwing something into the air on the moon will also fall, but slowly. The weightlessness of astronauts in space is due to the fact that the speed of the spacecraft reaches the first cosmic velocity, getting rid of the attraction of the Earth. Every mass thing in the world has a gravitational pull, and if there was no gravity, wouldn't the moon have already scattered like a cloud of ash in the universe?

The first should have been: man-plucked, and the second should have been: the gravitational pull of the earth

Because it's cooked! Gravity? Is that the answer you want?

Force. The principle

The earth is attractive to gravitational forces

Come on, you, it's not a problem of this century, the old cows have been dead for so long......

Kindness! Find the information of the old cow and you will know

1 The apple is affected by the gravitational force.

Because the earth has a gravitational pull, everything can only fall from the sky, not fly into the sky. So when the apple is ripe, it falls to the ground.
