• MECHANICAL ENERGY.
-Kinetic energy is the energy associated to the movements
-Pontential energy is the energy that objects have when they´re moved from their stable
position of equilibrium.

• NUCLEAR ENERGY:
• -Nuclear fussion is when two nuclei join fprm a heavier nucleus.
• Nuclear fission Iis when a heavy nucleus is divided into two smallers nuclei.
