A balloon filled with helium or hot air is less dense than the surrounding air, causing it to float. The buoyant force acting on the balloon is greater than the force of gravity pulling it down, allowing it to defy gravity and float upwards. This principle is known as buoyancy, based on Archimedes' principle, which states that an object will float if it is less dense than the fluid it displaces.
What else can I help you with?
What are the two forces that affect a hot air balloon?
The two forces that affect a hot air balloon are buoyancy and gravity. Buoyancy is the force that lifts the balloon due to the difference in densities between the hot air inside the balloon and the cooler air outside. Gravity acts to pull the balloon back down toward the ground.
Why does a balloon drop to the ground?
A balloon drops to the ground because of gravity, which is a force pulling objects towards the Earth's center. The air inside the balloon is less dense than the surrounding air, causing it to be less buoyant and leading the balloon to fall due to gravity.
What happens when you drop a balloon?
When you drop a balloon, gravity pulls it down towards the ground. As it falls, the air inside the balloon is pushed out through the opening, causing the balloon to deflate and eventually land on the ground.
What does gravity do push or pull or both?
Gravity causes things to fall to the ground. I believe it can push or pull things to the ground, to the center of the magnetized earth.
What force is activated because of the mass of the airplane and works to pull an airplane to the ground?
Gravity

Why can't you feel the pull of gravity?
You are asleep? When you walk, do you feel the ground? That's gravity.
If a weather balloon pops do the instruments fall to the ground?
Yes, if a weather balloon pops, the instruments attached to it will fall to the ground. These instruments are usually designed to withstand the impact of landing and are typically equipped with parachutes to slow their descent.

What is one way you can demonstrate gravity here on earth?
I don't know um.... put helium in a balloon and the balloon will float in the air
What is another word for force of gravity?
the stuff that keeps us on the ground :)
Does gravity affect a hot air balloon?
Yes. Without gravity, a hot air balloon would rise infinitely. You could never return to the ground. Balloons tend to hover more or less. The force of the air pushing up on the balloon and the force of gravity pulling down on the balloon are usually very close to one another. This keeps the balloon at a steady height, unless you heat the air in the balloon, or let it cool.
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.
Skydiving might feel like flying, but pretty soon ___ will pull you down to the ground?
