    Friction
In summary, the conversation discusses the possibility of a soccer ball catching fire if kicked with superhuman strength. It is mentioned that the material of the soccer ball is important in determining its flammability and that objects moving at high speeds such as airplanes and tracer rounds can also catch fire. The conversation ends with a suggestion to calculate the velocity needed to create the temperature required for the soccer ball to catch fire.

let's say i kicked a soccer really strong(and let's say i have insanely super human strength) , is it possible for the soccer ball to catch fire , and if it is at what speed?

Let me answer you with two questions:
(1) How hard could you kick a soccer ball without bursting it?
(2) What material is a soccer ball made of and what happens to that material as it warms?

Airplanes have to be traveling about mach 2 (1400 mph) before they start to worry about airframe heating.

If you get the soccer ball moving fast enough, it will most certainly burst into flames.

Roll down the window on the shuttle and hold your soccer ball out in the wind during reentry, and your soccerball will quickly look like a very large, neglected marshmallow in a campfire.

You don't have to be going that fast though, the temperature at which the soccerball bursts into flame is simply the ignition point of whatever it is made of. Leather?

Now all you need so is get someone to calculate the velocity that would create that temp on an object that size and shape.

just think of a tracer round

which is a actual example of something flying so fast it catches fire

What? :eek: They're made with magnesium or phosphorus! They're not burning due to friction!
 

FAQ: Can an object travelling really fast catch friction?

Can an object travelling at the speed of light experience friction?

According to Einstein's theory of relativity, objects with mass cannot travel at the speed of light. Therefore, they can experience friction.

How does the speed of an object affect the amount of friction it experiences?

The faster an object travels, the more friction it tends to experience. This is because as the object moves through a medium, it pushes against the particles in the medium at a higher speed, causing more resistance and thus more friction.

Is friction the same for all objects regardless of their speed?

No, friction is not the same for all objects. The amount of friction an object experiences depends on various factors such as its speed, weight, surface area, and the medium it is moving through.

How does friction affect the speed of an object?

Friction acts in the opposite direction of an object's motion, causing it to slow down. This is why it is necessary to continually apply a force to keep an object moving at a constant speed when it is experiencing friction.

Can an object travelling really fast overcome friction?

Although friction can slow down an object's speed, it is possible for an object to overcome friction and continue moving at a constant speed. This is typically achieved by using a constant force to counteract the frictional force acting on the object.
