Understanding the Concepts

* Work: Work is done when a force causes an object to move a certain distance. It's calculated as the product of force and displacement.

* Force: The force applied to the book is 1 Newton (N).

* Displacement: The distance the book is lifted is 2 meters (m).

Calculation

Work (W) = Force (F) × Displacement (d)

W = 1 N × 2 m

W = 2 Joules (J)

Answer: The work done when lifting the book is 2 Joules.
