Study Notes

Chemical Energy

Energy stored in the bonds of atoms and molecules.
Found in food, biomass, petroleum, and natural gas.

Nuclear Energy

Stored within the nucleus of atoms.
Released through nuclear fission (splitting) or fusion (combining) of nuclei.
Nuclear power plants predominantly utilize uranium fission to generate electricity.

Thermal (Heat) Energy

Created from atomic and molecular vibrations; faster movement equates to higher energy and temperature.
Also referred to as heat energy.

Gravitational Energy

A type of potential energy associated with gravity.
Energy is stored in objects positioned at a height relative to a lower position.

Law of Conservation of Energy

Energy cannot be created or destroyed, only transformed from one form to another.

Sound Energy

Energy resulting from the movement of vibrations through substances.
Travels in waves; generally contains less energy compared to other energy forms.

Elastic Energy

A form of potential energy stored in elastic objects like coiled springs or stretched elastics.
This energy accumulates when a force stretches or squashes the elastic material.

Light Energy

A form of electromagnetic radiation comprised of photons.
Produced when atoms in an object heat up; visible to the human eye and travels in waves.

Motion Energy

Also known as mechanical energy; energy contained in moving objects.
Greater speed in motion results in higher energy levels. Examples include wind, flowing rivers, and moving vehicles.

Electrical Energy

Involves the movement of electrons, fundamental particles within atoms.
Electricity is the flow of electrons through a conductor; lightning exemplifies electrical energy.

Radiant Energy

Also called light energy or electromagnetic energy; a type of kinetic energy.
Travels in waves and includes energy from the sun, x-rays, and radio waves.

Gravitational Potential Energy

Increases with height and mass of an object.
Higher position equates to greater potential energy, exemplified by a rollercoaster at the top of a hill compared to the bottom.

Elastic Potential Energy

Energy that is stored in objects when they are bent, twisted, or stretched.
Common examples include springs and rubber bands.

Potential Energy Overview

Defined as stored energy or energy associated with an object's position.
Key forms of potential energy:
- Gravitational
- Elastic
- Magnetic
- Chemical
- Electrostatic
- Nuclear

Kinetic Energy Overview

Considered the energy of motion.
Increases with an object's speed and mass.
Key components:
- Greater speed results in higher kinetic energy.
- Greater mass contributes to increased kinetic energy.
Example: A rollercoaster traveling at the bottom of a hill at peak speed has maximum kinetic energy.
