friction newton`s third law
... Work is a scalar quantity. (It is the dot product of two vectors.) Work is measured in joules. The joule is the standard unit of energy. Work and energy are equivalent – whenever work is done, there is a conversion of energy. Note: To calculate the work done, it is the applied force that concerns us ...
