energy transformations lesson 1

Cards (15)

what is energy? 
the ability to make objects move
how many forms of energy are there?
ten
what are the ten forms of energy?
thermal, magnetic, nuclear, elastic potential energy, kinetic, chemical, gravitational, electrical, sound, light
what is thermal energy?
the total energy of the moving particles in liquid, gas and solids
what is magnetic energy?
helps metal push or attract each other
what is nuclear energy? 
the stored energy at the center of particles. we split apart the particles releasing extreme amounts of energy
what is elastic potential energy?
energy that is stored in a bent or stretched object
what is kinetic energy? 
energy of motion
what is chemical energy? 
stored in food and fuel. it is how plants use sunlight, carbon dioxide, and water to create energy
what is gravitational energy? 
the stored energy of an object above earth
what is electrical energy? 
energy that moves between wires
what is sound energy?
energy we can hear
what is light energy? 
energy that our eyes can detect
what is the first law of thermodynamics?
energy is always conserved. it cannot be created/destroyed
what is the second law of thermodynamics?
in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than the initial state
