Question

Check if in this case, work is done and why?

A lady cooking food.

Answer 1

• Analyzing problem:

When a lady is cooking food:

• Force is applied.
• Displacement is zero.

• The formula of work done:

W=F$\times$d

where F = force applied to the object

and d =displacement of the object

• Conclusion:

In the case of a lady cooking food, we have force but the displacement is zero, so the work will not be done.

• Answer:

In this case, work is not done since the displacement is zero.
