chapter 13 Flashcards
the ability to cause change
energy
energy due to motion
kinetic energy
stored energy due to the interactions between objects or particals
potential energy
the amount of energy used as a force that moves an object over a distance.
work
sum of the potential energy and the kinetic energy in a system
mechanical energy
energy carried by sound waves
sound energy
the sum of the kinetic energy and the potential energy of the particles that make up an object
thermal energy
energy carried by an electric curent
electric energy
energy carried by an electromagentic wave
radiant energy
energy stored in and released from the nucleus of an atom
nuclear energy
law that states that energy can be transformed form one form to another, but it cannot be created or destroyed.
law of conservation of energy
a contact force that resists the sliding motion of two surfaces that are touching
friction
