Question

what does e=mc3 mean?

Answer 1

it is an equation by Albert Einstein showing that energy and mass are interchangeable. E is energy. M is mass. C is the speed of light thus energy. DOes that make sense @daniellecrook ?

Answer 2

i think you mean \[\epsilon=mc^2\]

Answer 3

and yes it is \(E=mc^2\)

Answer 4

not really can you explain a little bit more? @Jamierox4ev3r

Answer 5

It is the equation that helped prove that matter and energy are not separate but different forms of the same thing.

It means the energy contained in matter (e) is equal to the mass of the matter (m) times the speed of light (c) squared.

Answer 6

i dont understand math im so bad at it :(

Answer 7

it is an equation that energy and mass are basically undistinguishable. This formula is also often used to depict energy.

Answer 8

@ivanapen8 is you have any questions, I'd be glad to help you :)

Answer 9

oh ok i get it now thank you i will vote you best response!

Answer 10

@Jamierox4ev3r aw thank you

Answer 11

no problem, welcome to Openstudy!

Answer 12

@Jamierox4ev3r How is the speed of light = energy?

Answer 13

well light, regardless of the forms, produces energy and often times heat as a by-product.

Answer 14

If what you are saying is true based on the foundations and laws of physics then \(\bf E = c\) should suffice. We don't even the mass and there is no need to square the speed of light either. @jamierox4ev3r

Answer 15

@jamierox4ev3r your explanation leaves much to be desired. @daniellecrook it is an equation from Einstein's theory of special relativity that relates the mass of a body at rest to its rest energy. It is a specialized form of the broader energy-momentum relation:$$E^2=(pc)^2+(m_0c^2)^2$$

Answer 16

@oldrin.bataku Did you just look at that up?

Answer 17

@genius12 no hes smart af so u can leave

Answer 18

sorry @jamierox3ev3r i gotta give best reponse to @oldrin.bataku

Answer 19

@ivanapen8 Sorry sir but I'm here to learn. It's best if you do the same too.

Answer 20

@genius12 no it's taught in a basic high school physics class that touches on special relativity. It is more elementary than Lorentz and Poincare groups, that's for sure.

Answer 21

It's taught at around the same time the Lorentz factor is introduced to explain time dilation, length contraction, etc. for bodies moving at relativistic speeds in inertial reference frames

Answer 22

What's p in the equation?

Answer 23

As stated in its title, it is the momentum of the body.

Answer 24

I know what quantity does p represent?

Answer 25

tbh this was a joke post @genius12 you can leave

Answer 26

I just told you it is the (scalar) momentum of the body.

Answer 27

@oldrin.bataku How is momentum a scalar quantity?

Answer 28

clearly it is the magnitude of the momentum vector
