friction converts __________ energy into ___________ energy.
kinetic/thermal
potential/kinetic
chemical/potential
potential/chemical

Explanation:

Friction acts on moving objects (which have kinetic energy). As friction opposes the motion, it causes the object to slow down. The work done against friction results in an increase in temperature (thermal energy). Kinetic energy (due to motion) is thus converted into thermal energy (due to heat).

Answer:

Kinetic/Thermal
