Understanding Work
Work is done when a force causes an object to move a certain distance. It's calculated using the following formula:
* Work (W) = Force (F) x Distance (d)
Applying the Formula
* Force (F) = 30 N
* Distance (d) = 3 m
* Work (W) = 30 N * 3 m = 90 Joules (J)
Answer
The force of 30 N exerted over a distance of 3 m does 90 Joules of work.
