It's an image that you posted on an image board to start a new conversation, typically with a targeted question, but because you didn't I'm shitposting

E (Energy) = M (Mass) C (Constant/ Speed of Light) squared. Or roughly that mass and energy are the same.

its a formula, just read the terms out

So if my chocolate bar weighs 100 g and I multiply that with c squared I'll calculate the "energy" of my chocolate bar?

>> No.10288923

>>10288915
apparently

>> No.10288928

>>10288915
As long as the chocolate bar is at rest.

its about 9,000,000,000,000,000,000 joules

>> No.10288974

>>10288915
thats the energy of the rest mass of the chocolate bar

>> No.10289088

>>10288957
It would be same number with different gravity?

>>10289088
The energy due to rest mass has absolutely nothing to do with gravity.

>> No.10289097

>>10289091
Is kinetic energy affected by gravity or it's rest mass also?

>> No.10289104

>>10288852
>>10288838
Now set p equal to zero...

>> No.10289124

>>10289097
What exactly are you trying to ask? Of course kinetic energy is affected by gravity, just hold an object in the air and let go. Rest mass is invariant.

>> No.10289153

quick question, since momentum changes depending on observer, energy would too right?

watching a train pass youd say its momentum is large, and being on the train you would say it doesnt have any momentum

What's the difference between "energy" and "mass/speed of light"?

>> No.10290479

you know that force = mass x acceleration, right?
well Einstein said that force is just another version of energy and energy is mostly photon based. and photons travel at the speed of light (c).
so you replace force by energy (E) and acceleration by c^2 (acceleration is the variation of speed, and since the speed of light is constant, it's just c x c / 1).
