Elastic/Strain Potential Energy
There is the potential for work being done when the spring is stretched or compressed for the spring to go back to its original length/position
7
Chemical potential energy
Energy stored in the bonds of atoms and molecules.
Anything that can be burnt and undergo chemical reactions has chemical potential energy.

Poll
At the top of the roller coaster (position A) the carriage has lots of __________________
Kinetic energy
Potential energy
23
Multiple Choice
As the carriage descends to position B, the GPE is transferred into _______________ and speeds up.
Chemical energy
Kinetic energy
Light energy
Sound energy
24
Multiple Choice
Between B and C, the carriage keeps ________________ as its GPE is converted into KE.
decelerating
moving constantly
accelerating
flying
25
Open Ended
If you ignore any _________________ or friction between the carriage and the track, then all GPE the carriage had at A will be converted to KE when it reaches C.
26
Multiple Choice
A real carriage loses some energy through friction on the way down the hill.
It needs to have enough ______________ left at point C to carry it up the hill again to D.
power
GPE
KE
27
KINETIC ENERGY
28
DEFINITION OF KINETIC ENERGY
The energy that an object has because it is in motion (moving).
All moving object has kinetic energy
The magnitude of the kinetic energy depends on the speed (velocity) and mass of the object.
