Question

A force of 100 N acts through a distance of 25m.Calculate the work done ?

Answer 1

$\sf \Large Solution!!$

Work = Force × Distance

Work = 100 N × 25m

Work = 2500 J or 25 × 10² J (SI unit of work done is joule)

Answer 2

${\mathtt{\underline{Given}}}$

• force
• distance

${\mathtt{\underline{To\:Find}}}$

• work

${\mathtt{\underline{Solution}}}$

$\mathtt{\implies\color{green}{we \:know \:that\: Work \: done \: is\: given \:as}}$

${\underline{\boxed{\sf{\color{grey}{W= F× s}}}}}$

where

• F denotes force
• W denotes work done
• s denotes distance

$\mathtt{Substitute \: the \: values \: in \: the \: formula}$

$\sf{\implies W = 100 × 25 } \\ \\ \sf{\implies W = \color{orange}25000 \: Joule}$

More to know !!

✏️Work done is defined as the product of magnitude of force acting on the body and the displacement in the direction of the force.

✏️Energy is defined as the ability to do work

✏️SI unit of energy and work done is same - Joule.

✏️workdone = Newton x metre 1 Joule

✏️ 1KJ = 1000 J
