#19600# joules

Gravitational potential energy is given by:

#"GPE"=mgh#

where;

#m# is the mass of the object

#g# is the gravitational acceleration of the object

#h# is the height risen in meters

So, we get:

#"GPE"=1000 \ "kg"*9.8 \ "m/s"^2*2 \ "m"#

#=19600 \ "kg m"^2"/s"^2#

#=19600 \ "J" \ (because 1 \ "J"=1 \ "kg m"^2"/s"^2)#
