Hi all, i am trying to figure out if work done by gravity is positive or negative on an approaching meteor,
I have used W(1->2) = integral (1->2) F(gravity) dot dr. and got a result of (GMem/r2) - (GMem/r1).
Were G is gravity, Me is Earth mass, m is meteor mass and r1, r2 are initial and final radius respectively.
As (GMem/r2) > (GMem/r1) the result has to be positive right?
any help is appreciated :)
thank you
