SUMMARY
The work done by a 0.47N force pushing a 0.026kg pencil over a distance of 0.26m is calculated using the formula Work = Force x Distance, resulting in 0.1222J. The force of friction, measured at 0.23N, does not directly affect the work calculation since it acts against the motion but does not alter the work done by the applied force. The discussion clarifies that while friction opposes motion, it does not change the work done by the applied force in this scenario.
