right the question im finding tricky is:(adsbygoogle = window.adsbygoogle || []).push({});

by considering a body doing work against gravity, moving up a hill, determine whether work done is scalar or vector?

(2 mark question)

so i've draw like a triangle an arrow for force at an angle theta form the horizontal which has an arrow along for displacement d.

so i do d.F.cos theta = work.

but how does that justify that work is a scalar? im completly lost.
