Respected all,
If i push an object on the floor and drag it say 2 m in a straight line with force y. then the work done is force times displacement.
that is 2y.
first doubt
which formula is correct one
work = force multiplied by displacement
or
work = force multiplied by distance.
since most websites say ... work = force multiplied by displacement
hence
in my given example both the displacement and distance is the same. so ill get the same answer.
but
now if i push my box in a circle track and bring it back to the starting point . the distance traveled might be say 20 meters
but the displacement will be 0 meters.
so what will be my work done.
according to the above formulas
it can be either
20 y joules
or
0 joules
which is correct .
is it work done or not
