|
|
|
radiation

Explanation:
Detailed explanation-1: -Friction between two surfaces causes kinetic energy from moving surfaces to be converted into thermal energy.
Detailed explanation-2: -If the moving sand hits an obstacle, it stops due to the friction created by the contact and its kinetic energy is then transformed into thermal energy, or heat.
Detailed explanation-3: -Smooth surfaces, rubbed together, slide past each other with very little conversion of mechanical energy to thermal energy. Rough surfaces, on the other hand, exert a lot of frictional force on each other and convert mechanical energy into thermal energy much more rapidly.
