P3

Chemical Energy

Energy stored in food, batteries, and fuel.

Kinetic Energy

Energy possessed by moving objects.

Thermal Energy

Energy associated with hot objects.

Strain/Elastic Potential Energy

Energy stored in stretched, squashed, or twisted materials.

GPE/Gravitational Potential Energy

Energy stored in objects at high positions.

Atomic/Nuclear Energy

Energy stored in atoms.

Law of Conservation of Energy

Energy cannot be created or destroyed.

Unit for Measuring Energy

Joules (J).

Energy Diagrams

Visual representations of energy flow, such as Sankey diagrams.

Efficiency

Measure of how well a machine performs, ranging between 0 and 1.

Insulation

Slows down the rate of energy transfer out of a house by heating.

Conduction

Transfer of energy through materials, with metals being good thermal conductors.

Convection

Transfer of energy through fluids by creating convection currents.

Radiation

Transfer of energy through a vacuum, with different absorption rates based on surface properties.

Rate of Energy Transfer

Depends on thickness, thermal conductivity, and temperature difference.

Formula of Gravitational Potential Energy

Calculation for GPE.

Formula of Kinetic Energy

Calculation for kinetic energy.

Non-Renewable Energy

Energy sources like fossil fuels that will eventually run out.

Renewable Resources

Energy sources like solar and wind energy that do not deplete.

Biofuels

Fuels made from animal waste or non-food plants, considered carbon neutral.
