Today we defined 7 kinds of energy:
Mechanical
mechanical energy can be considered either kinetic (moving object) or potential (stored energy based on position). The image above shows objects exhibiting kinetic and potential energy.
Thermal
all of the energy from the random motion of the particles that make up an object
Chemical
the energy that holds atoms together in a molecule or compound
Electrical
the energy of moving electrons
Sound
the energy caused by an object's vibrations
Light
the energy produced by the vibrations of electrically charged particles
Nuclear
the energy that holds protons and neutrons together
Tonight's homework is to provide an example of each kind of energy discussed and present evidence for including it in one category or another. Here are two examples:
Ex 1: I would say that a car driving down Broadway is showing kinetic energy because it is in motion.
Ex 2: A stereo playing music is a form of sound energy, because the sound comes from the vibration of the speakers.
