Challenging Shani's Art Class Pose: Did She Really Do Any Work?

Which describes the work Shani did while she posed?

She did no work while she posed because she did not move the torch or the book.

Understanding Work in Physics

Work in physics is defined as the product of the force applied to an object and the distance over which the force is applied. If an object does not move when a force is applied, no work is done on that object.

Applying Physics Concepts to Shani's Art Class Pose

When Shani posed as the Statue of Liberty for her art class, she held a torch above her head with her right hand and a book against her side with her left hand. Although it may seem like holding these items for ten minutes would require a lot of effort, from a physics perspective, no actual work was done. This is because Shani did not move the torch or the book in any vertical direction. She maintained a static position throughout the pose, exerting a force to hold the items up but not causing them to move. Therefore, no work was done in the physics sense of the term. In conclusion, while Shani may have felt tired at the end of the art class session, it was not due to the physical work of lifting the torch and book, as no work was actually done in the physics context. This example demonstrates how understanding basic physics concepts can help us analyze and explain everyday situations that may seem physically demanding but do not involve work in the scientific sense.
