rubbing handsMechanical energy converted to thermal energy
Mechanical energy can be easily converted to other types of energy. Thermal energy is, to a great extent, wasted energy - it can no longer be converted to other types of energy.
It is converted into thermal energy, or heat.
Thermal energy can be converted into alot of things just go find out what it is.
Most of it will be converted to heat, via friction.
Chemical energy is being converted to thermal energy which is then converted to mechanical energy and finally to kinetic energy which moves the car. Kinetic energy is then converted to thermal energy in the brakes to stop the car.
Electrical energy is converted into thermal and mechanical energy
If 92 J of electrical energy are converted into 92 J of mechanical energy in an electric motor, then all of the electrical energy is being converted into mechanical energy. No thermal energy is being produced in this scenario. The efficiency of the motor in this case is 100%, meaning all the input energy is being converted into useful work without any energy loss in the form of heat.
The rest of the thermal energy is typically lost as waste heat, which is dissipated into the surrounding environment. This heat energy is not harnessed to do work and is considered a form of energy loss in the system.
Rub your hands together and they feel warm, right? That's it, rubbing your hands is using mechanical energy, which is by friction then converted to thermal energy (heat).
In a car engine, the chemical energy stored in the gasoline is converted to thermal energy through combustion. The thermal energy is then converted to mechanical energy as the pistons move and drive the vehicle. Finally, the mechanical energy is transferred to the wheels to propel the car forward.
When mechanical energy is lost to friction, it is converted into thermal energy due to the heat generated by the friction. This thermal energy dissipates into the surroundings, which is why the original mechanical energy is no longer in its mechanical form.
