Here's why:
* Work is defined as force multiplied by distance: Work (W) = Force (F) x Distance (d)
* You've given us the force (10 N), but we need the distance (d) to calculate the work.
To calculate the work done, you need to provide the distance the object is pushed.
For example:
* If the object is pushed 5 meters, the work done is:
Work = 10 N x 5 m = 50 Joules (J)
