it is -ve when the body is going up but +ve when the body is falling. g is not 10 if on anyother planet.
and acc. is not 10 in air resistance.

These notes are very precise and easy.

awesome notes! but in the the formula to find resultant force, why is it R^2 = F1^2 + F2^2 + 2F1F2Cos theta? we're basically using the cosine rule so shouldnt it be R^2 = F1^2 + F2^2 - 2F1F2Cos theta?
