List the nine forms of energy that you learned about in this sec­ tion. explain why these are not the only possible categories of energy.

There are nine forms of energy, they are the ff:
*Kinetic - energy resulting from the objects in dynamics
*Potential - energy resulting from a still object's shape, position,etc.
*Mechanical - the resulting energy from both potential and kinetic energy
*Thermal - energy from a kinetic energy of particles inside an object
*Chemical - energy resulting from a certain arrangement of atoms
*Electrical - energy from moving electrons
*Sound - energy from vibration of object to object
*Light - energy from electrically charged particles
*Nuclear - energy resulting from an atom's nucleus

It is called the medulla oblongata or people usually call it medulla. it is the lower half of the brain stem continuous with the spinal cord.
