Question

List four different forms or types of energy. Give one example of a conversion from each of these forms to another form.

a) Kinetic, potential, thermal, and electrical; kinetic to potential, thermal to electrical.
b) Mechanical, chemical, nuclear, and electromagnetic; mechanical to chemical, nuclear to electromagnetic.
c) Gravitational, elastic, sound, and magnetic; gravitational to elastic, sound to magnetic.
d) Thermal, nuclear, sound, and electrical; thermal to nuclear, sound to electrical.

Answer 1

Energy can be kinetic, potential, thermal, or electrical, and it can be converted from one form to another, like from kinetic to electrical in a hydroelectric dam.

Step-by-step explanation:

Energy can take various forms, including kinetic, potential, thermal, and electrical energy. These forms of energy can be transformed from one type to another. Here are four different forms or types of energy and examples of conversions between these forms:

1. Kinetic energy: The energy of motion. Example: A roller coaster traveling downhill converts potential energy into kinetic energy.
2. Potential energy: The energy stored in an object due to its position in a force field, such as gravity. Example: A drawn bow has elastic potential energy that converts to kinetic energy when the arrow is released.
3. Thermal energy: Energy an object possesses due to the random motion of its atoms and molecules. Example: A steam turbine converts thermal energy from steam into mechanical energy.
4. Electrical energy: Energy caused by the flow of electric charge through a conductor. Example: A hydroelectric dam converts the kinetic energy of falling water into electrical energy.
