Energy by Mind Map: Energy

1. Energy conversions

1.1. Space shuttle:chemical potential energy --> kinetic energy and gravitational potential energy --> thermal energy and sound energy

1.2. Pile driver: A weight (the driver) is lifted up to the top of the rig. The weight now has potential energy. As it falls the potential energy becomes kinetic energy (moving energy). When it strikes the post (pile/piling) at the bottom, the energy is used to drive the post farther into the ground.

1.3. Green leaves: Light energy+Heat energy—> Chemical potential energy

2. Definition of energy

2.1. The capacity or power to do work, such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another. It is measured by the amount of work done, usually in joules or watts. See also conservation of energy, kinetic energy, potential energy. Compare power, work.

3. Different forms of energy

3.1. Kinetic Energy

3.1.1. New node

3.2. Potential Energy

3.2.1. Gravitational

3.2.2. Elastic

3.2.3. Chemical

3.3. Thermal energy

3.4. Electrochemical Energy

3.5. Electrical Energy

3.6. Electromagnetic Energy

3.7. Sound Energy

3.8. Nuclear Energy

4. another energy conversion

4.1. Chemical energy from fossil fuels (coal, oil and natural gas) can be converted into heat energy when burned. The heat energy may be converted into kinetic energy in a gas turbine and finally into electrical energy by a generator. The electric energy may subsequently be converted into light, sound or kinetic energy in our homes through various household appliances.
