Document Summary
W int total work done inrrdetheoystemby interaction forces : gravitational potential. Energy : ug = mgy for problems , start by writing - The mechanical energy the object undergoes does not change as vertical motion. The only change on an in gravitational potential energy depends objects displacement . vertical: forces always perpendicular to the motion do notaffect the system "s energy . The normal force is always perpendicular to the motion. Friction increases the thermal energy of the system by. The distance of does surface have not the to fiction be y - oriented. For a system with energy a fiction applies to both gravitationalpotential principlebecomes energy the. A k t b ug t a eth. = 0 for problems, start by writing - = d k t a ug t d eth q = f.
