#"1 kJ"#

Work done is given by

#"Work = Force × Displacement"#

#"Work = 500 N × 2 m = 1000 J = 1 kJ"#

#1000# joules or #1# kilojoule

Work is given by the equation,

#W=F*d#

#F# is the force in newtons

#d# is the distance moved in meters

Here, the force is the weight of the box. So, we get:

#W=500 \ "N"*2 \ "m"#

#=1000 \ "J"#

We can convert it to kilojoules if we want to. Note that #1 \ "kJ"=1000 \ "J"#.

#:.=1 \ "kJ"#
