Why does the Earth attract the apple and the apple at the same time does not attract the Earth (the Earth does not move to the apple)?
I see an apple falling down :)
That's because you are standing on the Earth and are moving along with it. The Earth does not move relative to you.I see an apple falling down :)
Flor said:Is it because the intensity of gravitational field (g) of Earth is much bigger than the intensity of gravitational field of an apple? I can give you another question - what happens if the Earth radius will expand for example 1 x 10^30 times? Then the Earth will fall on apple! Is it true? :)
Flor said:I know, but is it observable? Or what is the best way to explain what we observe? I see an apple falling down :)
The gravity of an apple is significantly less than the gravity of the Earth. The Earth's gravity is approximately 9.8 meters per second squared, while the average apple has a gravity of about 0.2 meters per second squared. This means that the Earth has almost 50 times more gravitational pull than an apple.
Apples, and all objects, fall to the ground when dropped because of the Earth's gravitational pull. Gravity is a force that attracts objects towards each other. The Earth is much larger and has more mass than an apple, so it exerts a greater gravitational force on the apple, causing it to fall.
No, the gravity of an apple is too small to have any significant impact on the Earth's orbit. The Earth's orbit is determined by the gravitational pull of the sun and other large objects in our solar system. The apple's gravity is negligible in comparison.
Yes, the Earth's rotation does have an effect on the gravity of an apple. The faster an object rotates, the weaker its gravitational pull becomes. This is known as the centrifugal force. However, the effect is so small that it is not noticeable in everyday situations.
In terms of the Earth's overall gravity, the gravity of an apple is insignificant. The Earth's gravity is determined by the mass and density of the entire planet, not just one small object like an apple. However, the Earth's gravity does have a slight influence on the apple's gravity, as it is affected by the Earth's mass and rotation.
