True!
define visible spectrum
the most intense energy that produces colors from red to violet
What is an example of kinetic energy?
T/F: internal energy can be increased by compressing a substance into a smaller volume
true!
What are the two types of potential energy?
Gravitational & Chemical!
define work
a mechanical process of transferring energy from one machine or person to another
What is an example of potential energy?
Define internal energy
the sum of all the KE in a substance
On the electromagnetic spectrum, the longer the wavelengths, the ________ the energy.
lower!
Define fission
What is an example of thermal energy?
varies; energy from anything that has been heated up
E = mc2
What are the 6 types of energy?
Thermal, Nuclear, Gravitational PE, Chemical PE, Kinetic, and Electromagnetic Radiation
define conduction
when vibrating atoms in solids cause nearby atoms to vibrate too
what is an example of nuclear energy?
varies; energy emitted by fusion or fission
How does temperature affect atoms thus affecting the KE of a substance?
the hotter the substance, the faster the atoms move, the more KE the atoms have
Albert Einstein called this a quanta but today we call is a ________.
Photon!
define geothermal energy
the thermal energy in that ground that is stored in power plants
what is an example of electromagnetic radiation?
varies; energy from the sun
What is the law of conservation of energy?
energy can be neither created nor destroyed, only changed in form
