Newtons to Joules question.

[FloweryAlex]

Pretty simple, a character instructs a golem tackle with 20,000 Newtons of force, and then gives it a human shape and it delivers the same amount of energy "compressed" in a punch.

N=J/m^2

So would I need to calculate the m^2 of the fist, and thus divide the Newtons by it to know how much energy that punch packed?

For exemple, assuming a 10 cm wide and 8 tall fist (random aproximations) I'd get= 20,000/(0.1*0.08)=2500000 J

Bump.

No, Newtons is Joules/Meter. I think you need to multiply the force by the distance traveled in meters. A tackle of 20,000 N across a distance of 1 meter, would be 20,000 J. But this isn't a really good way to calc the energy of the punch. If you have timeframe and distance it's better to use Kinetic energy (Mass in kg*Speed in m/s*Speed in m/s)/2.

Oh, I see, my bad.

The golem was 3 meter tall nd made of concrete (with asphalt coating, but I don't lnow how thick that was) moving at mach 2.

Actually a one Joule = a Newton-Meter. The potential energy required to launch a newton one meter higher is one Joule.

 

[Dvorak1902]

That should be around 780 kg, going at 686 m/s. It's lends 183,000,000 J which is Small building level.

Thank you, I'll make a blog then.

Welp, here it is if you want to see it:
