Question

derivation of work ?

Answer 1

$work \: done =$

If force is variable then use this equation

⬇️⬇️⬇️

✨✨∫ F.ds✨✨

F–»Force.

ds–»small displacement


If Force is constant then use this equation -

➡️Work done= F×S

Answer 2

heya dear !!
_______:__


work is said to be done when a applied force causes some displacement.

w=f×s

f=forse
s=displacement
w=work

its mathematical expression

w = f cos theta × s

______________

there are three cases

◆positive when cos is 0°

◆negativewhen cos is 180°

◆zero wheb cos is 90°
