Given that:

• What will be the work done when a force of 20 newton displaces an object 4 metres in the same direction.

According to the statement:

• Force = 20 Newton
• Displacement = 4 metres

To calculate:

Solution:

Knowledge required:

• When the force and displacement are in same direction then the work done is positive.

• When the force and displacement are in different direction then the work done is negative.

• SI unit of work done is N/m because the SI unit of force is Newton that is N and SI unit of displacement is metre that is m, when be combined then it be N/m

• But to the honour of scientist that do maximum work on it, the SI unit of work done be Joule

Using concept:

Using formula:

Where, W denotes work done, F denotes force, S denotes displacement.

Full solution:

→ W = F × S

→ W = 20 × 4

→ W = 80 J

→ Work done = +80 Joule
