Can you apply kinetic energy to an object using its recessional velocity from the expansion of the universe?


I don't think so because then the kinetic energy would be relative to whatever you compare it to, what do you think?

No. Kinetic energy would be different for every different frame of reference.
Then there's the problem of the kinetic energy of stars moving at greater than lightspeed as seen from here.

Kinetic energy, like politics, is always local.
