12.1 Newton laws
- The dynamics link the acceleration of the body to the forces acting on it. Newton's laws apply to inertial counting systems and consider each body separately.
12.2 World gravity
Any body with a mass attracts, the gravity grows with the work of mass and loses proportionally to the square of the distance between the centres.
12.3. Rounding
- Even with the constant speed module, it's accelerated, because the direction of the speed is constantly changing.
