Understanding the Concepts

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

* Work (W) = Force (F) × Distance (d)

* Joules: The unit of measurement for work is the joule (J).

Applying the Information

* Force (F): 20 Newtons (N)

* Distance (d): 40 meters (m)

Calculation

Work (W) = Force (F) × Distance (d)

W = 20 N × 40 m

W = 800 Joules (J)

Answer: 800 joules of work were performed.
