The second equation is endothermic. the energy is listed in the reactants side. if it was a product it is exothermic. also the H value is negative exothermic positive endothermic
A result of friction is heat. Anytime friction occurs between two pieces of matter, some sort of heat is cretated. Rub your hands together with force, and you will notice that they become warm. This is because the kinetic energy of the moving mass is not lost when the object slows down due to friction. Instead, it is converted to heat.
Another result can be the creation of a charge of static electricity. For example rubbing a glass rod with a silk cloth will do this.
