# What is the work for a pulley system that lifts 9.8 N 10cm?

Nov 10, 2015

$0.98 J$

#### Explanation:

$\text{Work (J)" = "Force (N)" xx "Distance (m)}$ or
$W = F \times D$

The force is $9.8 N$
The distance is $10 c m$
The distance in metres is $\frac{\text{10cm}}{100} = 0.1 m$

$W = 9.8 N \times 0.1 m = 0.98 J$

Always be sure that you use the correct units. In this case, Newtons for the force and metres for the distance
