1.1 Forms of Energy flashcards

Potential Energy

Stored energy types: chemical, nuclear, electrical, gravitational.

Chemical Energy

Energy stored in atoms and molecules (e.g., coal, gas) released as heat and light when burned.

Nuclear Energy

Energy stored in the nucleus of an atom (e.g., sun/solar, atomic bomb).

Electrical Energy

Produced when charged particles move (e.g., batteries, lightning, wind turbine).

Gravitational Energy

Energy from all objects; greater in bigger objects (e.g., bird, tree branch).

Kinetic Energy

Energy of motion (radiant, thermal, and sound energy).

Radiant Energy

Travels in electromagnetic waves like x-rays and sunlight.

Thermal Energy

Vibration of atoms causing heat.

Sound Energy

Uses waves/vibrations in particles through mediums like air, water, or wood.

Energy Transformation

Occurs when energy changes from one form to another (e.g., wind to electrical, steam to electrical, sunlight to electrical energy).

All mechanical energy is divided into:

potential and kinetic energy

When a ball rolls downhill, potential energy is converted to:

kinetic energy

When a ball rolls downhill, some energy turns into(not kinetic):

friction, thermal, and sound energies

What occurs when energy changes from one form to another?

Energy transformation

Steam changing to electrical, or sunlight turning into electrical is called

energy transformation
