AQA Science: Glossary - Reproducible. A measurement is reproducible if the investigation is repeated by another person, or by using different equipment or techniques, and the same results are obtained. N.B. the same results implies identical, but in reality the same means that random error will still be present in the results.
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.
