The strong nuclear force
StrongWeakElectromagneticThe 4th force is gravity, but it seems to play no part in nuclius.
The Four Fundamental Forces are: * Gravity * Electromagnetism * Strong Nuclear Force (holds nucleus together) * Weak Nuclear Force (neutrino interactions induce beta decay) Most common forces like friction and drag and just objects pushing other objects are electromagnetic forces.
Strong nuclear force is the force that keeps the protons and neutrons in the nucleus of an atom. Being stronger than the electromagnetic force at very close distances, the strong nuclear force prevents the protons from repelling. Even more fundamentally, the strong nuclear force binds quarks together, which are the fundamental constituents of protons and neutrons.
Nuclear binding energy, more correctly called nuclear force or residual binding energy, is released when a nucleus transitions from a state requiring more nuclear force to one requiring less nuclear force. An example is where a heavy nucleus such as uranium is split into two lighter nuclei. Another example is where two light nuclei, such as hydrogen, is fused in to a heavier nucleus. In both cases, the nuclear force required to sustain the result is less than the original component(s), and the differential nuclear force (and the corresponding mass) is released.
The energy released when a nuclear power plant generates heat to generate steam to generate electricity. The energy released when a nuclear weapon detonates.
Strong nuclear force and weak nuclear force. The strong nuclear force overcomes the repulsion of the positively charged protons in the nucleus, holding it together. The strong nuclear force also holds the quarks together that make up protons, neutrons, etc. The weak nuclear force is responsible for beta decay.

-- gravity -- electrostatic force -- weak nuclear force -- strong nuclear force
a nuclear force that is stronger than normal
Two common sources of nuclear energy are the fusion reaction in the Sun, and the fission reaction in various nuclear power plants. Both release binding energy (Strong Atomic Force) which manifests, primarily, as heat.
