Once the cylinder starts moving, its gravitational potential energy decreases as it loses height.
I notice its kinetic energy increases — both translational (1/2 m v^2) and rotational (1/2 I ω^2) grow as it speeds up.
It changes because potential energy is being converted into kinetic energy; if the cylinder rolls without slipping and no non‑conservative forces do work, the total mechanical energy (PE + KE_trans + KE_rot) stays the same.
If there is slipping or friction/air resistance doing work, once the cylinder starts moving the total mechanical energy decreases instead, because some of the lost potential energy is converted into thermal energy rather than kinetic energy.
