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) x Distance (d)

* Force of Gravity: The ball's weight (20 Newtons) represents the force of gravity acting on it.

Calculation

1. Force (F): 20 Newtons (the ball's weight)

2. Distance (d): 2 meters

3. Work (W): W = F x d = 20 N x 2 m = 40 Joules (J)

Answer: The work done when lifting the ball is 40 Joules.
