What is the difference between strong and weak force?

What is the difference between the strong nuclear force and gravity?

• Answer:

  There are several major differences between the strong nuclear force (SNF) and gravity. Range of interaction: Gravity's interaction range is infinite, the SNF's range is about 10-15 m. Strength: Within the SNF's range, it is about 1038 times stronger than gravity. Strength as a function of distance: Gravity's strength is proportional to 1/distance2, whereas the SNF's strength increases up to a certain distance, and then remains constant. Types of interacting particles: Both hadrons and leptons interact via gravity, while only hadrons interact via the SNF. There are more differences than these, but they involve gauge theory, which is beyond the scope of this answer.
