If you push a box on a horizontal plane with no friction at a constant rate, pushing it twice means do half work?
Homework Answers
If you push a box on horizontal table with no friction at constant rate twice that means you are applying 2F now on the box which was initially F only then it will double the work done as W= Fnet d, where d = displacement so here Fnet =2F so new work done is twice not half for same displacement.
