Unit 5 Energy Flashcards

Front

Electrical energy (electricity)

Back

The energy of moving electric charges.

Front

Electric motor

Back

A device that contains a rotating electromagnet that changes electrical energy to mechanical energy. Includes blenders and washing machines.

Front

Generator

Back

A device that uses electromagnetic induction to induce electrical current by rotating loops of wire through a magnetic field.

Front

Mechanical energy

Back

Sum of potential and kinetic energy in a system.

Front

Nuclear energy

Back

The energy stored in the nucleus of an atom.

Front

Potential energy

Back

Stored energy based on position and chemical composition.

Front

Sound energy

Back

A type of mechanical energy, movement of energy through substances in longitudinal (compression/rarefaction) waves.

Front

Light energy (radiant or electromagnetic energy)

Back

The energy that travels in transverse waves.

Front

Kinetic energy

Back

Energy in the form of motion depending on the mass and velocity of the moving object.

Front

Heat energy (thermal energy)

Back

Energy that comes from internal vibrations of atoms and molecules.
