Energy and Metabolism. In efiect, the kinetic energy, hence the momentum, of a … When an atom absorbs a photon, it jumps up to a higher level; the difference in energy of the two levels must be equal to the energy of the photon. Perhaps the easiest way to describe kinetic energy is by looking at the typical roller coaster. An atom in a lower energy state can absorb light of frequency ν and thereby be promoted to a higher energy state, provided hν = ΔE, where ΔE is the difference in energy between the two states of the atom.
