energy Flashcards
(12 cards)
mechanical
energy transfer
when a force transfers energy
electrical
energy transfer
when energy is transferred by an electrical current
thermal
energy transfer and store
-energy from a hotter object is transferred to a colder object
radiation
energy transfer
energy transferred as a wave (light/sound)
conduction
-when a solid is heated particles vibrate and collide
-energy is transferred
convection
-when a liquid/gas is heated
-liquid/gas becomes less dense
-therefore energy is transferred
kinetic
energy store
energy due to movement
elastic
energy stores
energy stored in a stretched object
gravitational
energy stores
energy stored in an object due to position in the gravitational field
thermal
energy stores
energy due to heat
power
energy transfer
rate of energy transfer
equation for power
power= energy/time
