If i apply force to an object, but the object is too heavy to have moved, will i still have done work?
yaa
@aceace
confusion?? because w=fs
force is applied and displacement is also occur
@aceace
but there is no displacementas there is too much mass then will there have been work done?
it depends on where your definition of "work" is focused.
no movement, no work done... \[\int\limits_{a}^{a} F*dx = 0 \] ...no matter what F is
The phrase "i did work" still unclear. Only force do work. If you refer word ""I" to the "force you used to push the wall", then work is zero. But there's another force when you push the wall that does work. That's why you feel tired even if the wall isn't moving :)
work done = force * displacement so if object is not moving then you have done no work done
no displacement in the direction of force, no work done. even if you died pushing the object hard. ^_^ No displacement along the direction of force means no work done.
w=\[\int\limits_{0}^{d}\]f.ds...hence if displacement is zero,no work is said to be done in physics...
