Sliding friction torque does dissipative work on the force-bearer, transforming the kinetic energy of the bearer into internal energy and others of the bearer. Sliding friction countertorque does dissipative work on the applying body, transforming the kinetic energy of the bearer into internal energy and others of the applying body. In the experiment, the dissipative work done by sliding friction torque on the bearer is measured and calculated, the increase value of the internal energy of the bearer is measured and calculated, and the increase value of the internal energy of the applying body is measured and calculated. The consistency between their respective dissipative work and their respective internal energy increase value is compared.
