Both.
-- The gravitational force is always actually a pair of forces.
-- They act in both directions, on both bodies, and they're equal.
-- Whatever your weight is on Earth, that's also the Earth's weight on you.
-- When you jump out of an airplane, you accelerate toward the Earth, and
the Earth accelerates toward you.
(Of course, since the Earth's mass is something like 59,740,000,000,000,000,000,000 times
as much as your mass, your acceleration is 59,740,000,000,000,000,000,000 times as much
as the Earth's acceleration toward you.)
You and the Earth attract each other with an equal and opposite force. The Earth is so massive that it appears to stay fixed regardless of what you do.
Both. Do some reading on Newton's Third Law! If Earth attracts us, then we must needs attract Earth as well.
The Earth. The mass of the Earth is much larger than your mass.
At the center of a sphere, for every dot of mass attracting you toward it, there'sanother dot of mass at exactly the same distance from you in exactly the oppositedirection, attracting you toward it and canceling out the first one.
Gravitation force makes the Earth move around the sun and also makes the moon go around the Earth. Our weight is the gravitational force of the Earth acting on us. For example; the gravitational force of the moon is about one-sixth that of the Earth.
yes the moon is only about one-fourth the size of earth
Because gravity is the force of attraction between two objects, and the strength of the force depends on the distance between them. If the Earth is one of the objects and the other one leaves the Earth, then the force of gravity it feels is certainly going to change.
one-fourth of your weight on earth
When two bodies attract each other the larger one exerts the larger force because it contains more matter. Every particle of matter in the Universe is attracting every other. So the Earth exerts the stronger force on the Moon. The Space explorers have shown that on the Moon they weigh about one sixth of what they weight on Earth.
There are gravitational forces between you and every other thing in the universe. The nearer you are to the thing, the stronger the gravitational force is. You stay on the ground because the Earth is the biggest thing anywhere near you, and the nearest one. So the force attracting you to the Earth is stronger than the force attracting you toward anything else.
yes. gravity is the force of one object attracting another
Gravity always works equally in both directions. The Earth and the object each feel a force. The two forces attract each object toward the other one, and they're equal. The amount of force is what we call the object's 'weight' on Earth. Nobody ever mentions the fact that the Earth's weight on the object is the same number. -- The easiest way to measure the force attracting you toward the Earth is by using a bathroom scale. -- The easiest way to measure the force attracting the Earth toward you is by turning the scale over. -- You'll find that whatever you weigh on Earth, the Earth weighs the same on you.
When you moves straight from the surface of the Earth toward the moon, the force of gravity attracting you to the Earth decreases, and the force of gravity attracting you to the moon increases. The Earth's gravity is the stronger one until you're about 73% of the way to the moon, and from there the moon's gravity is stronger. So, from the time you leave the Earth, the net gravitational force on you decreases, and becomes zero when you have completed about 73% of the trip. From that point until you reach the moon, the gravitational force increases again, and when you reach the moon, the force on you is about 1/6 as strong as it was on the Earth, but pulling towards the Moon.
You're measuring one of the pair of gravitational forces between the Earth and the object. The strength of the forces depends on the mass of the object and the mass of the Earth. It also depends on the distance between their centers, but that's typically just the radius of the Earth (the distance from the Earth's center to the surface). The one we read on the scale is the force attracting the object to the Earth. It's what we call the "weight" of the object on Earth. The other force in the pair acts in exactly the opposite direction. That one is the force attracting the Earth to the object. We don't have to measure it because it has exactly the same strength as the first one. Nobody ever talks about it, but if we did, we would have to call it the Earth's weight on the object.
A voltage. That acts like a force on electrons (or other charged particles), pushing them away from one end, and attracting them to the other end (of a battery, for example).A voltage.

They don't "stick", any more than a person "sticks" to the Earth. In both cases ... gravity and magnetism ... there is a pair of mutual forces, one on each object, attracting it to the other object. If you simply apply force in the oppposite direction, and your force is any amount greater than the attractive force, the objects will separate.
The Earth exerts the greatest gravitational force on you because it is the most massive object you are closest to. The Earth exerts a force equal to your weight. The other objects exert gravitational forces but are not very noticeable because they are either low in mass or separated from you by great distance.
meteorites are one force when they impact. However, the key force acting on the moon is the force of gravity. The gravitational force is = G (m1 m2)/r2. Where G is the universal gravitational constant, m1 is the mass of one object, earth let's say, and m2 is the mass another object, say the earth. "r" is the distance between the two objects. The earth mass is larger, which is why it holds the moon in an orbit around itself. But the moon still effects the earth with tidal forces on the oceans and atmosphere.
You subtract the smaller force from the larger one.
