| - | The Newtonian formalism is a framework that allows us to predict how a system will evolve. | ||
| - | |||
| - | The basis of it is summarized by three laws, commonly called "Newton's laws of motion": | ||
| - | |||
| - | * **First law:** No force is needed to keep an object moving. If an object is at rest, it will remain at rest unless a force acts on it. Similarly, if an object moves with some constant velocity, it will keep moving unless a force acts on it. | ||
| - | * **[[equations:newtons_second_law|Second law]]:** The way the movement of an object changes depends only on two things: its mass and the total force acting on it. | ||
| - | * **Third law:** Whenever an object exerts a force on another object, inevitably this second object will also exert a force of equal magnitude on the first object. | ||
