Chemical, thermal and elastic energy

Chemical potential energy is the energy stored inside molecules.

When coal is burned, the chemical potential energy stored in a bond between two carbon atoms is released as thermal energy.

Thermal energy refers to the vibrations of the particles inside an object. Hot objects that have lots of thermal energy are used to do work.

In many power stations, steam at very high temperatures does work on turbines making them rotate at high speeds.

Elastic potential energy is the energy stored inside a solid that is compressed, stretched or deformed.

When you stretch a rubber band you are increasing its elastic potential energy.

 The elastic energy stored in the stretched bow is used to make the arrow fly through the air
