# Which problems led Newton to three laws of motion?

How did Newton come up with the three laws of motion? Are these laws are true of newton, or they are of Galileo.

• Please read Wikipedia's history section on Newton's laws of motion. The first law is vaguely attributable to Galileo, the second to Huygens, and the third to Newton himself. But it is treating them as a whole and building a system of physics around them that's Newton's main contribution, even if he did not come up with a single one of them. By the way, in the original drafts Newton had five or six laws. – Conifold May 15 '17 at 20:28
