safiya places a 5.okilogram brick on chair in the classroom.the chair is 1.o meter off the ground.what is the gravitation potential of the brick if it falls off the chair?remember that gravity equals 9.8 meter per second squared.

physics 
drwls,
P.E. = M g H,
where H is the height above the floor.
With your M, g and H units, the comoputed energy will be in Joules
