Kinetic energy for rotational motion
WebAug 20, 2024 at 22:00. @John Rotational kinetic energy generally is not conserved. The total energy of a closed system is conserved. And the angular momentum is conserved (what is not energy). I did not censor your question, I voted it up, I voted to "leave open", and tried to answer it. Web27 aug. 2024 · Rotational Kinetic Energy Eω = 1 2Iω2 , is the energy of a chemical entity associated with rotation, where ω is the rotational frequency (how fast the molecule spins) and I is the moment of inertia (in a sense, its resistance to spinning, the farther apart the hydrogen the greater I, the closer together, the smaller I.
