Thank you for clarifying this. I guess my question is: does it mean that when gravitational potential energy is calculated (I guess this also applies for electrical potential energy), you have to assume the object(s) doing the work remain stationary (in an inertial frame of reference)?
If that...
Hello,
I haven't learned a lot of physics and math, but I don't know how I misunderstand the following concepts:
Why is the gravitational potential energy of a system of two bodies described in one term instead of two? If each body in a two-body system effects a gravitational force on the...
