Forms of energy Flashcards
energy
the ability to do work or cause change
mechanical energy
energy produced by moving parts
electrical energy
the energy produced when electrons move from one place to another
light energy
visible energy that travels in waves. Light energy can move through empty, airless
space. Light waves always travel in a STRAIGHT line!
thermal energy
the energy of heat. This is caused by moving particles in a substance.
sound energy
a form of energy produced by vibrations that we can hear
conductor
a material that transfers heat or energy easily
insulator
a material that reduces or prevents the transfer of heat or energy
kinetic energy
the energy of an object in motion
potential energy
the energy that is stored in an object
friction
a force between two surfaces rubbing against each other
gravity
the force that pulls objects toward each other
energy transformation
the process of energy changing from one form to another
The Law of Conservation of Energy
Energy can never be created or destroyed, it can only be transformed
