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?

Answer 1

Multiply the two numbers. That will be the answer, in Joules

Answer 2

but what about gravity? Why not 15x9.81x.22?

Answer 3

15 N is mass *acceleration. In this case, acceleration= gravity.

Answer 4

Time them together without 9.8
