Answer 1

$\huge\mathbb\red{ANSWER}$

Workdone

__________☑☑

Workdone is given as the dot product of force and displacement .

It is denoted by W

W = F . S cos @

@ is the angle between applied force and displacement

✍F is the force applied .

✍S is the displacement .

✍Unit of workdone is Joule .

✍Workdone can be positive , negative or zero according to value of angel @ .

☑☑If the value of angel @ = 90

then the workdone is zero

because cos90° = 0

if the angle @ = 0 then the workdone is positive

because cos 0° = 1
