*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]].

*A firework is fired upwards and comes to rest at its maximum height. [[Mechanical Energy Transfer|Mechanical energy transfer]] due to the [[force]] of [[weight]].

*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.

*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.
