Which form of energy primarily accounts for the mechanical energy that “disappears” when a wooden block slides to a stop across a rough horizontal table?
(a) Sound energy carried away as acoustic waves generated by the rubbing surfaces
(b) Elastic potential energy stored in microscopic deformations within the block
(c) Thermal energy produced at the interface between the block and the table
(d) Gravitational potential energy gained as the block rides over surface irregularities
