Energy Flashcards
What are the types of potential energy
Gravitational, chemical, elastic, nuclear potential energy
What are the 3 ways heat can be transferred
Conduction, convection, radiation
What is conduction
Heat being transferred between objects in direct contact
What is convection
Heat transferred between fluids in a circular motion
What is radiation
Heat waves spreading outwards from the source
What is the law of the conservation of energy
Energy can never be created or destroyed, it can only be transferred or transformed
What is the formula for finding the efficiency of something
useful energy output/total energy input x 100
What is exothermic heat
Something releasing heat
What is endothermic heat
Something taking in heat
What is a load (circuts)
Something that consumes energy
What is a conductor
A material that allows electrons to flow through easily
What is a insulator
A material that resists the flow electrons
