Section 1- What is Energy?
Chemical Energy
a form of potential energy that depends on the position and arrangement of the atoms in a compound
Light Energy
energy produced by the vibrations of electrically charged particles
Nuclear Energy
energy that comes from change in the nucleus of an atom
Kinetic Energy Formula
mass X volume 2/ 2
Mechanical Energy Formula
potential + kinetic
Energy
the ability to do work
Mechanical Energy
the amount of work an object can do because of the object's kinetic and potential energies
Kinetic Energy
the energy of an object that is due to the object's motion
Electrical Energy
the energy of moving electrons
Potential Energy
the energy that an object has because of the position, shape, or condition of the object
Thermal Energy
the kinetic energy due to random motion of the particles that make up an object ( temperature is a measure of thermal energy)
Sound Energy
vibrating objects transmits energy through the air around it
Gravitational Potential Energy Formula
weight X height
fission
when a nucleus splits
fusion
when nuclei join together
Gravitational Potential Energy
when you lift an object, you do work on it. You transfer energy to the object
