At what speed does stuff burn up?

The drag force and surface area also play a role in determining the speed at which an object will burn up in the atmosphere. This means that the material and design of an object are important factors in determining its burn up speed.

hi, everyone.
something iv been pondering recently, is there a set speed at which something burns up in the air/atmosphere, or is it more to do with the surface area of the object traveling through the air, which would mean more of a drag force which means that the extra energy transforms to heat which causes the burn up? which would mean its more of a material and design problem for burning up in the air/atmosphere?

any relevant information would be great. thanks

It is a combination of several things. Obviously an object with zero velocity will generally not burn up unless it is self combustible. For a moving object, the velocity it will burn up will depend on several things, including its shape and composition.
 

1. How does the speed of burning affect the amount of heat produced?

The speed of burning does not necessarily affect the amount of heat produced. The amount of heat produced depends on the material being burned and the amount of oxygen available for combustion.

2. At what speed does stuff burn up in space?

Without the presence of oxygen, combustion cannot occur in space. However, in the process of re-entry into Earth's atmosphere, objects can reach speeds of over 17,500 miles per hour, causing intense friction and heat that can lead to burning and disintegration.

3. Is it possible for things to burn up instantly?

No, it is not possible for objects to burn up instantly. Burning requires a process of combustion, which involves the release of energy and the production of heat. Even in cases where objects may seem to burn quickly, there is still a process of combustion occurring.

4. Can the speed of burning be controlled?

The speed of burning can be controlled to some extent by adjusting factors such as the amount of oxygen and fuel present, as well as the temperature. However, the chemical properties of the material being burned ultimately determine how quickly it can combust.

5. What factors affect the speed at which things burn up?

The speed at which things burn up can be affected by various factors, including the presence of oxygen, the type of material being burned, the temperature, and the surface area of the object. Other external factors such as wind or pressure can also impact the speed of burning.
