an object weighing 15 newtons is lifted from the ground to a height of 0.22 meter. What is the approximate increase in the object's gravitational potential energy?
Answered by drwls
Multiply the two numbers. That will be the answer, in Joules

but what about gravity? Why not 15x9.81x.22?
Answered by Devron
15 N is mass *acceleration. In this case, acceleration= gravity.

Time them together without 9.8
