Question

what is the unit used to express work?
grams per cubic centimeter (g/cm³)
newton meter (n·m or n m)

Explanation:

To determine the unit of work, recall the formula for work: \( W = F \times d \), where \( F \) is force (in newtons, \( N \)) and \( d \) is distance (in meters, \( m \)). So work is measured in newton - meters (\( N\cdot m \)). The unit \( g/cm^3 \) is for density (mass per unit volume).

Answer:

newton meter (\( N\cdot m \) or \( N\ m \))
