What force makes a hot air balloon rise up into the air?
The upthrust exerted by surrounding air on the balloon.
How does Archimedes principal work in hot air balloon?
Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In a hot air balloon, the heated air inside the balloon is less dense than the cooler air outside, creating a buoyant force that lifts the balloon. This principle allows the hot air balloon to float in the air by displacing enough air to lift its weight.
What happens when the force acting on a hot air balloon are balanced?
When the force acting on a hot air balloon is balanced, the balloon will remain at a constant altitude. This means that the buoyant force on the balloon is equal to the gravitational force acting on it. As a result, the balloon neither rises nor descends.
Why does a hot air baloon float?
Raising the air temperature inside the envelope makes it lighter than the surrounding (ambient) air. The balloon floats because of the buoyant force exerted on it. This force is the same force that acts on objects when they are in water
WHAT ARE THE TWO FORCES ACTING ON THE hot AIR BALLOON?
The two main forces acting on a hot air balloon are buoyant force, which lifts the balloon due to the density difference between the hot air inside the balloon and the cooler air outside, and gravity, which acts to pull the balloon downward.

Is a hot-air balloon buoyant?
Yes, hot air balloons are less dense and therefore buoyant ============================================ Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.

What forces are used in a hot air balloon?
In a hot air balloon, buoyant force (lifting the balloon due to the density difference between the hot air inside the balloon and the cooler air outside) and wind force (pushing the balloon in a particular direction) are the primary forces involved in its movement. Additionally, the pilot can control the vertical movement using the burner to heat the air inside the balloon.
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.
On a perfect fall day you are hovering at low altitude in a hot-air balloon accelerated neither upward nor downward The total weight of the balloon is 17500?
The buoyant force exerted by the air on the balloon must be equal to the weight of the balloon in order to maintain a constant altitude. This means that the buoyant force is 17500 N and it is balancing the weight of the balloon. If the buoyant force decreases for any reason, the balloon would start to descend.
What forces are used ina hot air balloon?
Hot air balloons use the force of gravity to descend and the force of buoyancy to ascend. The buoyant force is created by heating the air inside the balloon, making it less dense than the surrounding colder air. The air pressure inside the balloon also plays a role in controlling the altitude of the balloon.
How does a hot air balloon go down?
A hot air balloon can descend by either releasing hot air from the balloon envelope or by opening a vent at the top of the balloon to allow some of the hot air to escape. This reduces the buoyant force that is keeping the balloon in the air, causing it to descend slowly. The pilot can control the descent rate by carefully managing the release of hot air.
How do unbalanced forces affect a hot air balloon?
Unbalanced forces can cause a hot air balloon to accelerate in the direction of the stronger force. For example, if the upward buoyant force is greater than the downward force of gravity, the balloon will rise. If the forces are equal, the balloon will remain at a constant altitude.
