I think they create friction and that creates heat. I don't really know though, that was just a guess.
They transfer energy because as they gain heat which gives the particles more energy to move freely, the particles will inevitably collision into each other, so as this collision occurs the thermal energy is transfered to the newly hit particle, this would explain why heat is transfered quicker in solids, because the area between each particle is less than liquids and gases because it's particles are closely packed.
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
Isn't it because some of the energy gets transfered to thermal energy?
Yes and no. Kinetic is transfered to thermal all the time with friction. Sound and heat (thermal energy) are the usual outcomes. Be careful about using create, as the law of conservation of energy states the energy is transfered not created or destroyed.
Thermal energy can be transfered with three ways Conduction,Convection Radiation
Matter is needed to transfer thermal energy by conduction and convection. Conduction happens through a substance when there is a difference in thermal energies between regions. Convection is the movement within a fluid caused by hotter material to rise and colder material to sink and transfer heat.
It could be transfered to sound, thermal, and potential energy.

Convection is the movement of particles due to a gradient of energy. Heat energy is thus transfered by the moving particles.
it is transfered or turned into waste thermal energy
Thermal energy is the energy that comes from the heat of an object. It is the total kinetic energy of the particles within a substance, which is a result of their random motion. Temperature is a measure of the average thermal energy of the particles in a substance.
