Derivation for escape velocity (1 Viewer)

[theduckforces]

Do we need to know how to derive the formula for escape velocity? And if we do, what is the derivation?

 

[photastic]

Yes if they asked to find the escape velocity, you must derive the formula.

Should also derive the radius of the earth if you ever need to use it and it is not given

how?

awesome. Always amazed by what happens when you equate formulas in this topic

Thanks buddy!

If u think about it logically, kinetic energy is equal to or more than the gravitational force, which is required to escape the gravitational force of the planet ( definition of escape velocity (makes sense)
