1.) When a boy was skating, kinetic energy was high, and thermal energy was low.
2.) As the boy applied his brake pad, kinetic energy was decreasing and thermal energy was increasing.
3.) When the boy stopped, kinetic energy was low, and thermal energy was high.
4.) At all times, total energy = kinetic energy + thermal energy
hopefully my answered helped!
