A force F is exerted on an object of mass m through a distance d. A force twice as large (2F) is exerted on a mass 2m also through the distance d. Explain the relation between the amount of work done in the two cases
What will be an ideal response?
In this case, there are two possible answers.
(1) The force and displacement are parallel or antiparallel.
because the distance is the same, the force that is twice as large does twice the work.
(2) The force and displacement are perpendicular.
No work is done, no matter what.
