Energy Transfer Flashcards
List the 9 types of energy
Electrical Light Sound Kinetic Nuclear Thermal Gravitational Potential Chemical Elastic Potential
Give an example of Electrical energy
Whenever a current flows eg. in circuits
Give an example of Light energy
From the sun, light bulbs
Give an example of Sound energy
From speakers, anything noisy
Give an example of Kinetic energy
Anything moving, eg, a car
Give an example of Nuclear energy
release only from nuclear reactions eg, in nuclear powerstations
Give an example of Thermal energy
Flows from hot objects to cooler ones. Eg, an oven
Give an example of Gravitational Potential energy
Possessed by anything that can fall. Eg, a ball on a ledge
Give an example of Chemical energy
Possessed by foods, fuels, batteries etc.
Give an example of Elastic Potential energy
Stretched springs, elastic, rubber bands etc.
Which 3 types of energy are stored energy?
Gravitational Potential
Chemical
Elastic Potential
(because they are waiting for something, not doing anything)
What is the conservation of energy?
Energy can be transferred usefully from one form to another, stored or dissipated - but it can never be created or destroyed
Energy is only useful when…
It can be converted from one form to another
