Ah, so the shock wave behind it will have a equal speed as the object that created it? So if somthing is moving at mach 3 , the shock wave will be mach 3?

How would one calculate the speed of a shock wave or intensity? For example, let's say something with a mass of 10 kg, with a velocity of 1000 m/s, travling in a straight line ,in Earth's atmosphere, at sea level . what formulas would one use to figure this out? Thanks in advanced

I really have no true reason, it just has been a burning question for some reason, and thank you for clarifying this :)

I know this is a weird topic but the thought has pestered me lately. How much energy would it take to cut a large astronomical body in half (assuming its a uniform sphere). Let's say a object the size of the moon with the same overall density of the moon. Say the blade used to cut it is as hard...

Thanks for some clarification :)

How do scientists calculate or estimate the heat of a object in atmospheric re-entry in ° kelvin (the specific formula or formulas if any exist). I'm guessing it has to do with velocity and mass of the object but I'm not sure on the whole process Thanks in advanced :)

alright, I guess I'll just do some reading on line Appreciate the help

Ah that claifys things, and sorry I didn't specify what I ment in destruction, our convo was talking about a astroid striking earth, he said E=mc² is what is used used to measure it , it sounded suspicious so I came here to ask some more experienced people

I know the basics of E=mc² and it being mass energy, but someone told me its also used for projectiles and explosions how does it corrolate with destructive power ? Thank you in advanced

I see, I appreciate the help

I figured you would need to find a lot of variables like I was reading about the square inversed law, but i guess that formula does not associate with the topic at all?

Thank you, I didn't imagin it would be as simple as that

I'm new to physics I tried doing some research but I can't seem to fully grasp the concept. My question is, how would one find how much energy is needed to destroy a object a select distence away from the blast For example if a star when super nova and had a x amount of joules, and let's say a...
