Understanding Work

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

* Work (W) = Force (F) x Distance (d)

Applying the Information

* Force (F): 20 Newtons (the weight of the box)

* Distance (d): 5 meters (the height the box is lifted)

Calculation

* Work (W) = 20 Newtons * 5 meters

* Work (W) = 100 Joules

Answer: Lifting the 20 Newton box 5 meters off the floor requires 100 Joules of work.
