what does "conservation of energy" tell you about this? If the object you are moving acquires gravitational energy, where do you think it came from?

The relationship between work and gravitational potential energy can be described by the principle of conservation of energy. According to this principle, energy cannot be created or destroyed, but can only be transferred or transformed from one form to another. In the case of work, it is the transfer of energy from an external force to an object, resulting in a change in the object's energy.

In the context of gravitational potential energy, work is done when an object is moved against the force of gravity. This results in an increase in the object's gravitational potential energy, as it gains the ability to do work itself. The amount of work done is equal to the change in gravitational potential energy, as described by the equation W = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the change in height.

Conversely, if an object is allowed to fall due to the force of gravity, it will lose gravitational potential energy and gain kinetic energy. This demonstrates the transformation of energy from one form to another.

In summary, work and gravitational potential energy are closely related as work is the means by which gravitational potential energy is gained or lost. By understanding this relationship, we can better understand the behavior of objects in a gravitational field and calculate the amount of work required to change an object's gravitational potential energy.
