Question

In which of the following situations would the least work have been done?

Answer 1

Work = (magnitude of the force) x (distance in the direction of the force)

A 100-N force lifts an object 3 m.                ==>  (100 x 3) = 300 joules

B. A 250-N force moves an object 1 m.      ==>  (250 x 1) = 250 joules

C. A 25-N force moves an object 8 m.        ==>  (25 x 8)  =  200 joules

D. A 600-N force is applied to an object
    and moves it 0 m.                                   ==>  (600 x 0) = no work
                                                                           Winner ! Least work.
