Conversion of Energy - SS3 Physics Lesson Note

Energy can be converted from one form to another. The following are some common examples of energy conversions:

Thermal to mechanical energy: In steam power plants, heat energy from burning fossil fuels or nuclear reactions is used to produce steam that drives turbines, generating mechanical energy.

Chemical to electrical energy: Batteries convert chemical energy into electrical energy, which can then be used to power various devices.

Electrical to mechanical energy: Electric motors convert electrical energy into mechanical energy to power machinery and appliances.

Nuclear to electrical energy: In nuclear power plants, nuclear reactions are used to heat water, which then produces steam that drives turbines, generating electrical energy.

Solar to electrical energy: Solar panels convert energy from sunlight into electrical energy that can be used to power homes and buildings.

Wind to electrical energy: Wind turbines convert the kinetic energy of the wind into electrical energy that can be used to power homes and buildings.

Hydro to electrical energy: Hydropower plants convert the kinetic energy of moving water into electrical energy that can be used to power homes and buildings.

Mechanical to electrical energy: Generators convert mechanical energy, such as the energy from falling water or steam, into electrical energy that can be used to power homes and buildings.

Energy conversion is a critical process that allows us to use different forms of energy in various applications. The efficiency of energy conversion processes is an important consideration, as it can impact the cost and environmental impact of energy production and use.
