Dave ok I can accept c is the universises speed limit
what I don't understand is why a speed limit is any part of
why mass=energy or vice versa.
If a mass is converted into energy why does the speed of light
have anything to do with calculating how much energy there is?
Thanks - but
I ask the question because that's the question I'd like an answer to.
So perhaps someone else can explain the relationship ?
I realize it's tricky to explain some concepts.
And I'm not questioning that it IS the case.
I'm trying to understand why there is even a...
Curious
Why does the equivalence of mass/energy involve the speed of light at all?
Is it because Einstein discovered that this was simply the correct multiplier
or was there some other reason to connect the speed of light to the relationship?
Hi MrCedgy - thanks for the response.
You are right in that I can ignore the more intricate data such as friction etc. Put simply the final goal is to be able to point at a material and say something like "An english longbow arrow should be deflected by X cm thickness of Y material hanging...
I hope this is a good place to ask this:
I'm trying to model how an object such as a kevlar vest performs in stopping
a high velocity projectile such as a bullet.
I have only basic knowledge of energy and momentum etc. but can learn if directed.
I can calculate the Ke of the bullet...
