The scientific definition is defines work as a scalar. The definition of Work should recognize the Quaternion nature of Work, W = Wscalar + Wvector =[f,F] [d, D] = [fd -F.D, fD + Fd + FxD] . The definition of work is deceptively simple, but for accuracy it is perhaps better to approach this in stages. It is often stated too simply, i.e. Work equals force times distance.. It is necessary to clarify the vector nature in order to get the scientific definition.
