===About Energy Transfers===
: [[Energy]] can be '''transferred''' from one [[object]] to another or between [[Energy Store|energy stores]] within the same [[object]]. For example on a pool table when white ball hits another ball '''energy is transferred''' from the [[Kinetic Energy Store|kinetic store]] of the white ball to the [[Kinetic Energy Store|kinetic store]] of the other ball.
: There are 4 ways energy can be transferred;
*[[Mechanical Energy Transfer|Mechanically]] - By the action of a [[force]].
*[[Electricity|Electrically]] - By an [[Electrical Current|electrical current]].
===About Energy Transfers===
: [[Energy]] and be '''transferred''' between [[Energy Store|stores]] in a [[system]]. This may be between the different [[Energy Store|energy stores]] of a single [[object]] or between the [[Energy Store|energy stores]] of different [[object]]s within that [[system]].
: When there is an '''energy transfer''' [[energy]] is [[Conservation of Energy|neither created, nor destroyed]]. This means when that when one [[Energy Store|energy store]] decreases, one or more others must increase.
: [[Human]]s use '''energy transfers''' for a number of reasons but they usually result in some [[energy]] being '''transferred''' to an unwanted [[Energy Store|store]]. This is known as [[Wasted Energy]].
There are 4 ways energy can be transferred;
*[[Mechanical Energy Transfer|Mechanically]] - By the action of a [[force]].
*[[Electricity|Electrically]] - By an [[Electrical Current|electrical current]].
*[[Radiation|By radiation]] - By [[Light]] [[wave]]s or [[Sound]] [[wave]]s.
*[[Heating|By heating]] - By [[Thermal Conduction|conduction]], [[convection]] or [[Thermal Radiation|radiation]].
