Question

Define energy. Give examples (at least five) when one type of energy transforms into another type.

Answer 1

Energy:

1. Energy is described as the capacity to do work, or the ability to apply a force that causes an object to move.
2. Energy conversion is the transformation of energy from one mode to another mode.

Examples, of when one type of energy transforms into another type, are listed below:

1. Thermoelectric (Heat → Electrical energy)
2. Geothermal power (Heat→ Electrical energy)
3. Fuel cells (Chemical energy → Electrical energy)
4. Piezoelectric tranducers (Mechanical energy → Electrical energy)
5. Friction (Kinetic energy → Heat energy )
