Answer:

#"Joule (J)"#

Explanation:

What is the SI unit of work? And are you asking if it's the Newton?

#color(white)(aaaaaaaaaaaaaaa)"Work" = F*dcostheta#

Where
#"F = Force" (N or (kg*m)/s^2)#

#"d = displacement (m)"#

#costheta = "angle between the applied force and displacement"#

#---------------------#

#W = color(magenta)"F"*color(blue)"d"costheta#

#W = color(magenta)"N"*color(blue)"m"->color(magenta)(((kg*m)/s^2))*color(blue)"m"#

becomes...

#W = (kg*m^2)/s^2 #

so...

#1" Joule" = N*m = (kg*m^2)/s^2#

But scientists would rather use #"Joules (J)"# than write out #(kg*m^2)/s^2#
