Question

A force of 80 N displaces an object through 5 m in the direction of force. Calculate the work done?​

Answer 1

Given -

• Force = 80 N

• Displacement = 5 min

To find -

• Work done.

Solution -

Formula to calculate work done -

• Work = Force × Displacement

Substitute the given values.

⇛ 80 × 5

⇛ 400 J

$\large{\underline{\boxed{\sf{\red{Work~done = 400~J}}}}}$

━━━━━━━━━━━━━━━━━━━

Work -

• It is a force which causes a movement in a object.

• It is a scalar quantity.

• Its S.I. unit is joule.
