Hey..suppose i have the 9312 number. And 3 digit. Number can be represented by 9*10^3 + 3*10^2 + 1*10 + 2 how do i get the 10^2 ? (either 2 or 1000) ? do we need logarithms? thanks andre

Ok.... but since everything moves, (i checked wikipedia), then everything is subject to a force , and applying a force? thanks....

ooops forgot :)

you can't it doesnt exists...you arne't holding anything...for example, for apples or roses..zero of those two are equal...also because of infinity might be zero..for example the creation of the university

Is it possible, that one physics law is "Everything is in motion?" (since zero doesnt belong to nature)...if so, does that implies that black holes move?

What is the relevance of attributing a unit to a expression? does that mandate that the quantity is vectorial?! what is the relation between a joule and the fact that its possible a vector? And i still don't get it, h is not a vector , is distance " If you accept that energy, by definition, is a...

exorthaton -> the effect of applying the force Can you explain why? Particulary the U=mgh formula

But isn't energy the exorthation of force in a body?

If the energy is a vector, which as i understand for example, the potential energy , U=mgh, where g is the gravitational force, Then U is the product of scalars and vectors, so its a vector In that case being E a vector , can it be equal to mc2 (each are scalars). Like mulitplication of scalars...
