===Meaning===
An [[Energy Transfer]] is when [[energy]] moves from one [[Energy Store|energy store]] to another [[Energy Store|energy store]].
: When an [[object]] travels upwards the [[Gravitational Potential Energy Store|gravitational potential energy store]] increases.
The following are examples of '''energy transfers''' into the [[Gravitational Potential Energy Store|gravitational potential energy store]]:
*A ball starts in motion but comes to rest at its maximum height. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[force]] of [[weight]].
''[[Kinetic Energy Store]] of the ball → [[Gravitational Potential Energy Store]] of the ball.''
*A bullet firework is fired upwards and comes to rest at its maximum height. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[force]] of [[weight]].''[[Chemical Potential Energy Store]] of the gunpowder → [[Gravitational Potential Energy Store]] of the bulletfirework.''*An arrow is fired upwards and comes to rest at its maximum height. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[force]] of the bow on the arrow and the [[weight]] of the arrow.
''[[Elastic Potential Energy Store]] of the bow → [[Gravitational Potential Energy Store]] of the arrow.''
====Falling====
: When an [[object]] falls the [[Gravitational Potential Energy Store|gravitational potential energy store]] decreases.
*A ball is dropped and after bouncing a few times it comes to rest. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[force]] of [[weight]].
''[[Gravitational Potential Energy Store]] of the ball → [[Thermal Energy Store]] of the ball and surroundings''
*A trampolinist stars at a height of 2 metres and falls onto a trampoline stretching the springs. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[weight]] of the trampolinist and the [[force]] needed to extend the springs.
''[[Gravitational Potential Energy Store]] of the trampolinist → [[Elastic Potential Energy Store]] of the trampoline.''
====Collisions====
: When an [[object]] [[collide]]s with another [[object]] [[energy]] the [[Kinetic Energy Store|kinetic energy store]] of the first [[object]] decreases.
*A white ball hits a red ball on a snooker table. [[Mechanical Energy Transfer|Mechanical energy transfer]] due action [[force]] and reaction [[force]] between the two [[object]]s.
''[[Kinetic Energy Store]] of the white ball → [[Kinetic Energy Store]] of the red ball.''
*A tennis ball in collision with a wall. [[Mechanical Energy Transfer|Mechanical energy transfer]] due action [[force]] and reaction [[force]] between the two [[object]]s.
''[[Kinetic Energy Store]] of the tennis ball → [[Elastic Potential Energy Store]] of the tennis ball.''
*A sponge in collision with a wall. [[Mechanical Energy Transfer|Mechanical energy transfer]] due action [[force]] and reaction [[force]] between the two [[object]]s.
''[[Kinetic Energy Store]] of the sponge → [[Thermal Energy Store]] of the sponge and surroundings.''
====Acceleration by a Constant Force====
: When an [[object]] [[accelerate]]s the [[Kinetic Energy Store|kinetic energy store]] increases.
*A car [[accelerate]]s from rest. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to [[Driving Force|driving force]].
''[[Chemical Potential Energy Store]] of the [[fuel]]/[[battery]] → [[Kinetic Energy Store]] of the [[car]].''
*A skydiver [[accelerate]]s to [[Terminal Velocity|terminal velocity]] after jumping out of a plane.[[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[force]] of [[weight]].
''[[Gravitational Potential Energy Store]] of the skydiver → [[Kinetic Energy Store]] of the skydiver.''
====A vehicle slowing down====
: When an [[object]] [[decelerate]]s the [[Kinetic Energy Store|kinetic energy store]] decreases.
*A car applies the brakes. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to [[friction]].
''[[Kinetic Energy Store]] of the [[car]] → [[Thermal Energy Store]] of the brakes.''
*A ball rolls before coming to a stop. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to [[friction]].
''[[Kinetic Energy Store]] of the ball → [[Thermal Energy Store]] of the ball and surroundings.''
====Heating====
: When [[object]]s are [[heat]]ed the [[Thermal Energy Store|thermal energy store]] or the [[Internal Energy]] of the [[object]] increases.
*A water filled kettle is placed on a stove. [[Heating|Energy Transfer by Heating]] due to the stove being a higher [[temperature]] than the kettle.
[[Thermal Energy Store]] of the stove → [[Thermal Energy Store]] of the [[water]] and kettle.
*An electric kettle is connected to a car [[battery]]. [[Electricity|Electrical Energy Transfer]] due to the [[Electrical Current|current]] flowing from the [[battery]] to the kettle.
[[Chemical Potential Energy Store]] of the [[battery]] → [[Thermal Energy Store]] of the [[water]] and kettle.
===Examples===
The high [[temperature]] causes the [[Electrical Bulb|bulb]] to glow, [[emit]]ting [[Visible Light]]. This [[Visible Light]] '''transfers energy by radiation''' to the surroundings.
