Types of Energy

These flashcards cover various types and definitions of energy, including potential and kinetic energy, as well as specific forms and their measurements.

Energy

The ability of things to change themselves or to cause change in other things.

Joule (J)

The unit of measurement for energy, defined as 1 N⋅m or 1 kg m/s².

Kinetic Energy (KE)

Energy of motion, which depends on mass and velocity.

Potential Energy (PE)

Energy due to position or stored energy.

Elastic Potential Energy

Energy stored in objects that are stretched, compressed, or otherwise distorted.

Chemical Potential Energy (CPE)

Energy stored in chemical bonds of a substance.

Gravitational Potential Energy (GPE)

Energy due to an object's height and mass; calculated as PE = mass × gravity × height.

Thermal Energy

Energy associated with the vibration and movement of molecules, often felt as heat.

Radiant Energy

Energy carried by electromagnetic waves.

Sound Energy

Energy produced by vibrations that travel through a medium as sound waves.
