Energy

Energy

The ability to do work or to cause a change

The Law of Conservation of Energy

Energy cannot be created or destroyed. It can only be transformed.

Energy Chains/Transformations

A visual list of what form of energy was originally present and all the forms of energy it was transformed into

Example of energy chain

Plugging a lamp into a wall (Electrical to radiant)

Potential energy

Stored energy within an object or associated with its position

Kinetic energy

energy of motion

Mechanical energy (p+k)

The total energy of motion and the position of an object (Also includes sound energy)

Example of mechanical energy

A car

Radiant energy (K)

Also known as light energy- is produced by the vibrations of electrically charged particles

Example of radiant energy

A microwave

Chemical energy (P)

The energy of a compound that changes as its atoms are rearranged

Example of chemical energy

Food (clues are batteries, fire, chemical reaction)

Electrical energy (K)

The energy of moving electrons

Example of electrical energy

A lightbulb (clues are wires or outlet)

Nuclear energy (P+K)

The energy that comes from changes in the nucleus of an atom

Example of nuclear energy

Nuclear fusion in sun, Nuclear power plants use fission

Thermal energy (K)

Total energy of moving molecules - affected by the speed and number of molecules

Example of thermal energy

Ice cream melting on a hot day, hot springs, campfire, or cup of hot tea, water boiling
