Question

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

A man standing at a place and holding a suitcase in hand.

Answer 1

• Analyzing problem:

When a man is standing at a place and holding a suitcase in hand:

• Force is applied i.e. equal to the weight of the suitcase
• 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 man standing at a place and holding a suitcase in hand, 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.
