energy in the system Note that the total mechanical energy of the system is constant if we assume that there is no friction You will learn more about pendulums in 14 Loss of mechanical energy The oscillations of a pendulum eventually come to a stop, a bouncing ball comes to rest, and the heights of rollercoaster hills get lower and lower Where does the mechanical energy in such systems go Any object moving through the air experiences the forces of air resistance In a roller coaster, there are frictional forces between the wheels and the tracks When a ball bounces off of a surface, all of the elastic potential energy that is stored in the deformed ball is not converted back into kinetic energy after the bounce Some of the energy is converted into thermal energy and sound energy As in the cases of the pendulum and the roller coaster, some of the original mechanical energy in the system is converted into another form of energy within members of the system or transmitted to energy outside the system, as in air resistance Usually, this new energy causes the temperature of objects to rise slightly You will learn more about this form of energy, called thermal energy, in 12 The following strategies will be helpful to you when solving problems related to conservation of energy
