1.1. Gravitational Energy
1.1.1. depends in:
1.1.1.1. masses of two bodies
1.1.1.2. distance apart
1.1.1.3. gravitational constant
1.1.2. the gravitational potential energy that two bodies with a mass have in relation.
1.1.3. formula
1.1.3.1. U=m⋅g⋅h
1.1.3.1.1. U=gravitational energy(joules)
1.1.3.1.2. m=mass of the object accelerating(kg)
1.1.3.1.3. g=acceleration of the object (m/s)
1.1.3.1.4. h=distance between the bodies(m)

2. Strong Nuclear Force
2.1. It is the strongest but it has a short rage in which its particles should be really close to have an actual repercution.
2.2. Main Function
2.2.1. Hold together nucleons (+, neutral)
2.3. How it works?
2.3.1. It is created between nucleons in an interchange of mesons. (Pi)
2.3.2. To be effective it should has a distance of about a diameter of a proton.
2.4. F= G m1 m2/ r^2

3. There are four main and basic forces in energy.
4. Weak Nuclear Force
4.1. Stronger than gravity.
4.2. Effective only in very short distances (10-18m), because the particles involved are so big
4.3. Beta Decay
4.3.1. A neutron disappears and is replaced by a proton, an electron and a neutrino (anti-electron)
