Work is defined as force times It's almost too painful to watch. W equals F times D. In this definition, only the force in the direction of motion counts. If a wagon is pulled at an angle, only the horizontal part of the pull does any work. Work done in distance D is FH times D. No, no, sorry, this is not my table, sir. Whe ...
