Knowing Dommes that would work for some but you better at least be able to demonstrate a decent capacity in some stem branch. Engineering is a mixed bag because it’s great for degradation scenes but it is often a yellow flag
For those who dont understand the equation, E = Energy, specifically Kenetic Energy in this case, p = momentum, which is determined by mass and velocity, and m = mass. You wanna know something else? a^2 + b^2 = c^2 is the same fucking thing as E^2 = p^2 + m^2.
This isn't uncommon in lots of physics calculations where you are working at the same scales a lot and its cumbersome to keep carrying the constants around and it adds risk of making a mistake.
Think of it as assuming you are working in a system of units where you measure all your speeds relative to the speed of light. So rather than saying the speed limit of a road is 30mph you would say its .000000045c.
Just use the only practical unit of length, "lengthunit", which is equal to 299792458 meters (whatever those are...) times the only practical unit of time, "time unit", divided by a "second" (whatever that is...).
