In a vacuum, a balloon with helium (for example) would also fall down. The point is that gravity pulls on the surrounding air with more force, because it is heavier; this pushes the balloon up. The situation is similar to a boat floating in water. The water displaces the boat - pushing it up precisely because of gravity.
What else can I help you with?
Why do things that go up always come down?
Objects that go up always come down due to gravity, which is the force that brings objects back towards the Earth's surface. When something is thrown upwards, gravity acts as a constant force pulling it back down until it reaches the ground. This phenomenon is known as projectile motion.
When a ball is thrown away from the earth's center it will always?
due to newtons laws of gravity, all things that go up come down for example helium balloons and satellites
How does gravity hold things down?
We don't actually know. As far as we can tell, it boils down to "because that's how things are." Most theories of gravity at most push that back one step: "Because mass curves spacetime" "Why?" "Because that's how things are."
What is the force that makes things move?
The force that makes things move is known as mechanical force, which is the result of interactions between objects or systems. This force can be generated by a variety of mechanisms, such as pushing, pulling, friction, gravity, or electromagnetic interactions.
Why is weight affected by gravity?
Weight is affected by gravity because weight is the force exerted on an object due to gravity pulling it towards the center of the Earth. The strength of gravity determines the weight of an object; the stronger the gravitational force, the heavier the object will feel.
What is the force of the earth pulling things toward its surface?
The force of the Earth pulling things toward its surface is known as gravity. Gravity is what keeps objects, including us, grounded and gives weight to objects. It is a fundamental force in the universe that attracts all objects with mass towards each other.
Gravity speeds things up?
Yes; gravity is a constant force. It never loses its ability to "pull." A human being pulling a wagon on a rope would eventually not be able to run any faster. But gravity isn't like that. It's a constant energy, and can keep pulling faster, no matter how fast it is already pulling.

What does gravity do for the world?
Gravity is a force of attration.It is a pulling matter.Gravity holds up the earth without gravity we would be having comets every single day ,it holds things in place.
When a ball is thrown away from the earth's center it will always?
due to newtons laws of gravity, all things that go up come down for example helium balloons and satellites
Which force is responsible when a ripe fruit falls from a tree?
Of course, the gravitational pull of the earth is the prime factor here. The apple is being pulled to the centre of the earth, but in most cases is blocked by something .Example, the ground. Gravity is pulling everything toward it, but depending on how heavy it is determines how much force that gravity has over the object. For example: Gravity has more control over a car than a helium balloon, because the heavier the object, the more gravitational pull it conducts.
What is gravityy?
Gravity is a force pulling together all matter (which is anything you can physically touch). The more matter, the more gravity, so things that have a lot of matter such as planets and moons and stars pull more strongly.

What is the relationship between gravity and pressure in a nebula?
Gravity is responsible for pulling matter together in a nebula, leading to the formation of stars. As the matter in a nebula collapses under gravity, it increases in density and temperature, which in turn leads to an increase in pressure. The balance between gravity pulling matter inward and pressure pushing outward ultimately determines the fate of the nebula.

What are things that are gravity?
There are no things that are gravity. Gravity is a force that is associated with anything that has mass.
