What are the all the types of energy and their meanings
Advocard [28]

Thermal -Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy.

Nuclear - Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity.

Elastic - Elastic energy is a form of potential energy which is stored in an elastic object - such as a coiled spring or a stretched elastic band. Elastic objects store elastic energy when a force causes them to be stretched or squashed.

Chemical - Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas.

Electrical - Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas.

Radiant - Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays and radio waves.

Light - Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.

Motion - Motion energy – or mechanical energy – is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind, a flowing river, a moving car, or a person running.

Sound - Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate. There is usually much less energy in sound than in other forms of energy.

Gravitational - Gravitational energy is a form of potential energy. It is energy associated with gravity or gravitational force – in other words, the energy held by an object when it is in a high position compared to a lower position.

A young woman sees her doctor with complaints that the bones in her left knee regularly dislocate, or move out of their usual pl
Serga [27]

Answer:

Her knee ligaments are weakened or injured so they can't stabilize the bones

Explanation:

Ligaments are dense connective tissues that serve to connect bones to each other. Ligaments are made by definite arrangement of collagen fibers in particular pattern. Weakening or injury to ligament makes the joints unstable. Since ligaments are not strong enough to hold the bones together, weakened or injured ligaments lead to bone dislocation. The woman with complaint of regular bone dislocation in her left knee must have weak or injured ligaments that can’t stabilize the bones.
