Energy Transfer

A series of free Science Lessons for 7th Grade and 8th Grade, KS3 and Checkpoint Science in preparation for GCSE and IGCSE Science.

Energy Transfers
What is meant by conservation of energy?
How energy can be transferred from one store to another store.
First we explore the idea of conservation of energy and what is meant by a closed system.
Then we look at energy transfers in the case of pendulums. Finally, we see how energy can be dissipated.
The Law of Conservation of energy states that
Energy can be transfered usefully, stored or dissipated but it cannot be created or destroyed.

Energy Transfer Diagrams
An energy transfer diagram shows the input energy and output energies of a device. This includes all the useful and wasted forms of energy.
