Y8- Energy Adds Up Flashcards
Conservation of energy definition
energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
3 ways energy is transferred
- convection
- conduction
- radiation
Conduction and its process .
Conduction is energy transmitted through a material or substance .
-particles transfer energy by colliding, and vibrating each other.
Convention and its process
It is the transfer of energy as particles rotate ,taking turns in transferring the energy .
-as a fluid heats from the bottom ,up it rises ,whilst the colder ,denser fluid sinks to take its place and heat up - the process repeating.
Radiation and its process.
Radiation is energy transmitted through waves . This works through a vacuum.
Definition of charge
Store of energy
Energy and power - watts the difference .
- Energy can be stored , power cannot .
