1036 times the strength of the strong force, it is always attractive, and acts between any two pieces of matter in the Universe since mass is its source. Every body mass attracts gravitationally other. According to a famous legend, one day Newton was sitting under an apple tree, wondering about the force that holds the moon to Earth, when viocaer an apple. This event gave the key to discovering that degravedad force, the same as does the apple fall, is also the one that holds the Moon in orbit, and discovered the principle of universal gravitation.

Then it goes the Electromagnetism, its strength is less than 1% of that of the strong force, but it, like gravity, has infinite range. However, unlike gravity, the electromagnetism has both attractive and repulsive properties that can combine or cancel each other out. Whereas gravity is always attractive, electromagnetism comes in two charges: positive and negative. Two positive or two negative things will repel each other, but one positive and one negative attract each other. This can be neatly illustrated by magnets: two of the same "pole" will repel each other, but two opposite poles attract each other. It is long-ranged, but much weaker than the strong force. It can be attractive or repulsive, and acts only between pieces of matter carrying electrical charge.

The weak nuclear force is one of the less familiar fundamental forces. It operates only on the extremely short distance scales found in an atomic nucleus. The weak force is responsible for radioactive decay. In actuality, it is stronger than electromagnetism, but its messenger particles (W and Z bosons) are so massive and sluggish that they do not faithfully transmit its intrinsic strength, is responsible for radioactive decay and neutrino interactions. It has a very short range and, as its name indicates, it is very weak.

The strong nuclear force is the other unfamiliar fundamental force. Like the weak force, its range is limited to subatomic
