Types of Energy

The energy associated with the motion of an object. The faster an object moves and the more massive it is, the more kinetic energy it has.

Example: A moving car, a rolling ball, or a person running.

The energy stored in an object due to its position or configuration. It can be of different types:

Gravitational Potential Energy: Energy due to an object's height in a gravitational field.

Example: A rock at the top of a hill.

Elastic Potential Energy: Energy stored when an object is stretched or compressed.

Example: A compressed spring or a stretched rubber band.

The internal energy of an object due to the movement of its molecules; it is related to the object's temperature.

Example: Heat from a stove, the sun warming the Earth's surface.

The energy stored in the chemical bonds of molecules. This energy is released or absorbed in chemical reactions.

Example: The energy in food, gasoline that powers a car, or a battery in use.

The energy of electric charges moving through a conductor.

Example: Electricity powering devices like phones, computers, and household appliances.

The energy stored in the nucleus of atoms; it is released through fission (splitting of nuclei) or fusion (joining of nuclei).

Example: Energy released in nuclear power plants or in stars.

The energy carried by electromagnetic waves, such as visible light, X-rays, or microwaves.

Example: Sunlight, a lit lamp, or laser beams.

The energy transmitted through sound waves traveling through a medium (air, water, etc.).

Example: The sound of a guitar, a conversation, or the noise of an engine.

The energy stored in magnetic fields, capable of doing work on objects containing magnetic materials like iron.

Example: Magnets, electric motors, and generators.
