the ability to cause changes in matter, exists in many different forms.
the energy associated with the motion of the particles of matter, heat is the transfer of thermal energy.
energy transferred through electromagnetic waves such as visible light, ultraviolet light, or x- rays.
A type of radiant energy from the Sun that provides light and heat for Earth; solar energy can be used to generate electricity
energy stored within the chemical bonds of matter such as in food, fossil fuels, and substances that can burn
the energy flowing in an electric circuit; sources of electrical energy include batteries and generators
energy due to the motion and position of an object
the energy an object has due to its motion
stored energy related to the position of an object
Gravitational Potential Energy
energy stored in an object as a result of its vertical position or height
Elastic Potential Energy
Energy stored in elastic materials as a result of their stretching or compressing
Law of Conservation
Energy cannot be created or destroyed but it can change from one form to another form; the amount of energy you start with is the amount of energy you end with
the path through which electricity flows; electrical energy in a circuit can change to light, sound, heat, or motion by devices/loads added to the circuit
The flow of electrical energy through a circuit
the force of attraction or repulsion of magnetic materials
the area surrounding a magnet that applies a push or pull without actually touching an object
a current- carrying coil of wire that creates a temporary magnet; can be turned on and off by stopping the flow of electricity
a device that changes mechanical energy into electrical energy; produces an electric current when a coil of wire wrapped around an iron core is rotated near a magnet
Large wheel that rotates a magnet in a generator; can be turned by moving water, wind, or steam
a device that changes electrical energy to mechanical energy.
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
the emission or transmission of energy in the form of waves or particles through space or through a material medium.
