what energy store has moving energy
kinetic
what is thermal energy
an object with heat energy
what energy releases through chemical reactions
chemical
what is the energy that can fall
GPE (gravitational potential energy)
what is elastic potential energy
anything stretched
what are 2 charges that attract or repel each other
electrostatic
what is magnetic energy
2 magnets that attract or repel each other
what is nuclear energy
atomic nuclei react
what is the formula for KE (kinetic energy)
KE= 0.5 x mass x speed
what is the formula for GPE (gravitational potential energy)
change in GPE = mass x gravitational field strength x change in height
what is conservation of energy
energy can never be created or destroyed
what is a mechanical transfer
a force acting on an object
