Which energy transfer is transferred via a current?
electrical working
Which energy transfer is heat moving from one place to another through convection and conduction?
Heating by particles
Which energy transfer involves electromagnetic waves?
Heating by radiation
What is the principle of the conservation of energy?
Energy cannot be created or destroyed, only transferred from one store to another
What is the term used to refer to energy being lost to the surroundings?
dissapation
What is work?
Work is the energy being put onto an object by a force, i.e me pushing james
What is work done equal to?
The amount of energy transferred onto the object
what is work measured in?
joules (J)
what is the formula for work?
Work = Force x Distance
