Stores of Energy and Energy Transfers

Flashcards covering key vocabulary related to stores of energy, energy transfers, and efficiency concepts for energy in systems.

Gravitational Potential Store

Energy stored in an object due to its position above the ground, such as when it is lifted against gravity.

Elastic Potential Store

Energy stored when an object is stretched or compressed, like in a spring.

Thermal Store

Energy contained within an object due to its temperature.

Chemical Store

Energy stored in the bonds of chemical compounds, such as in fuels.

Kinetic Store

Energy possessed by an object due to its motion.

Magnetic Store

Energy stored in the magnetic field of two separated magnets that are either attracting or repelling each other.

Electrostatic Store

Energy stored in the electric field between two separated electric charges that are attracting or repelling each other.

Nuclear Store

Energy contained within the nucleus of an atom.

Energy Transfer

The process by which energy moves from one store to another, often when a system changes.

Energy Pathways

The methods through which energy is transferred from one store to another, including heating, electrical, radiation, and mechanical.

Efficiency

A measure of how much useful energy is converted from the total energy input into an appliance, expressed as a percentage.

Law of Conservation of Energy

The principle stating that energy cannot be created or destroyed, only transferred from one form to another.

Wasted Energy

Energy that is dissipated during a process and spread out, making it less useful.

Power

The rate at which energy is transferred or converted, measured in Watts (W).
