changes in matter
Energy
transfer of energy to an object by force
work
more massive the object is travelling the more energy it has
kinetic energy
energy stored based on retaliative position with in a system
potential energy
is the sum of kinetic and potential energy in an object that is used for work
mechanical energy
energy contained within a system that is responsible for its temperature
thermal energy
that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space
electromagnetic energy
energy that is associated with vibrations of matter
sound energy
can be used to move charged particles through a wire from a power plant to our homes etc.
electrical energy
Elastic energy occurs when objects are compressed and stretched, or generally deformed in any manner.
elastic energy
is released when bonds form in a chemical reaction, often producing heat as a by-product (exothermic reaction)
chemical energy
the energy released during nuclear fission or fusion, especially when used to generate electricity
nuclear energy
set of connected things or parts forming a complex whole
system
