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)

* Power: Power is the rate at which work is done. It's calculated as: Power (P) = Work (W) / Time (t)

Calculation

1. Calculate the work done:

* Work (W) = 6 N * 2 m = 12 Joules (J)

2. Calculate the power:

* Power (P) = 12 J / 3 s = 4 Watts (W)

Answer: 4 watts of power are expended.
