Some of the forms which energy can have, are:
- Thermal energy
- Kinetic energy
- Potential energy
- Electric potential energy
- Radiation
Some examples of transformations between different forms of energy, are:
- Potential energy to kinetic energy during the course of a roller coaster.
- Kinetic energy to thermal energy when an object decelerates due to friction while sliding on a surface.
-Kinetic energy to thermal energy when a meteor melts upon entering the atmosphere due to friction.
- Kinetic energy to electric potential energy in a generator.
- Electric potential energy to radiation in a digital screen.
- Electric potential energy to thermal energy in a light bulb.
- Thermal to kinetic energy in a heat engine.
Use these examples to identify energy changing forms around you and write a brief paragraph.
