Energy Vocabulary Flashcard

Front

Device that measures temperature.

Back

Thermometer: A device used to measure temperature, indicating how hot or cold something is.

Front

The sum of potential and kinetic energy in a system.

Back

Mechanical Energy: The total energy of a system, which is the sum of potential energy (stored energy) and kinetic energy (energy of motion).

Front

Form of energy also known as heat.

Back

Thermal Energy: The energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Front

The amount of kinetic energy in matter.

Back

Temperature: A measure of the average kinetic energy of the particles in a substance, indicating how hot or cold it is.

Front

Transfer of heat energy through waves.

Back

Radiation: The process of transferring heat energy through electromagnetic waves, such as sunlight.

Front

Transfer of heat energy through direct contact.

Back

Conduction: The process of heat transfer through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

Transfer of heat energy through fluids (liquids and gases).

Back

Convection: The transfer of heat by the movement of fluids, where warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

Energy stored in an object due to its position or state.

Back

Potential Energy: The energy that is stored in an object because of its position, condition, or configuration.

Front

Energy of motion.

Back

Kinetic Energy: The energy that an object possesses due to its motion, which depends on its mass and velocity.

Front

Energy produced by moving electric charges.

Back

Electrical Energy: The energy resulting from the flow of electric charge, often used to power devices.
