No... The spacecraft in your example does not have kinetic energy while coasting along on orbit. Instead, it posses potential energy. Potential energy and kinetic energy are not the same thing. Physics, thermodynamics stuff.
No, the World Trade Center buildings had potential energy from the energy required to lift the materials. That was converted to kinetic energy when the buildings collapsed. A spacecraft moving in space has kinetic energy from that movement.
“Potential” is the physics term for “volts”. Atoms can become ionized and thus can be short an electron or have an extra electron creating a physical need to equalize when in proximity. This creates pressure and depending on that pressure or potential electrons will flow producing watts aka work aka energy. You are saying that the gravity pulling a spacecraft towards earth is potential and the closer to the gravitonal source the greater the pull. Although there might be some kinetic energy due to the fact an object is in motion actually the weight of the object is a minor factor. The quantity of objects moving in relation to the conduit or conductor size is the calculable factor. A spacecraft coming into the atmosphere is not kinetic but potential energy because it is basically only 1 electron being pulled to the earth to equalize.
But like I said I’m not a physicist just an electrician so correction of clarification is welcome!
