energy stores Flashcards
what are the 9 types of energy?
light, heat, sound , kinetic, GPE, EPE,
nuclear, chemical, and electrical potential
why is sound not an energy store?
sound transfers in waves since it vibrates
what is the law of conservation of energy?
energy cannot be created or destroyed, only transferred.
what is light energy?
energy given off of the sun.
what is sound energy?
energy associated with vibrations of matter.
what is heat energy?
energy associated with the movement of atoms, ions and molecules.
what is kinetic energy?
energy that is contained in the movement of objects.
what is gravitational potential energy?
energy stored in an object which has been lifted off of the ground.
what is nuclear energy?
energy that is contained in the nucleus of an atom.
what is elastic potential energy?
energy stored in a stretched object.
what is electrical energy?
energy contained in charged particles.
what is chemical energy?
energy stored in bonds of molecules.
how do we measure energy?
using Joules (J)
1000 Joules = 1 KJ
