Problem
Show that the mechanical work done by a constant force acting on a particle is a scalar quantity.
Your answer should:
(a) Begin with the mathematical definition of work in terms of force and displacement.
(b) Introduce the appropriate vector operation and demonstrate why the result is independent of the orientation of the coordinate axes.
(c) Conclude explicitly why this proves that work is a scalar physical quantity.
