Formulate 1,2,3 Newton’s laws.

1 Newton’s law: a body is in a state of rest or uniform rectilinear motion, if other bodies (forces) do not act on it or the action of bodies (forces) is compensated.
2 Newton’s law: the acceleration of a body a is directly proportional to the force F, which acts on the body and is inversely proportional to the mass of the body m.
a = F / m.
The force F that acts on the body is equal to the product of the body’s acceleration a and its mass m.
3 Newton’s law: the force F12, with which one body acts on another, is equal in magnitude and opposite to the force F21, with which the second body acts on the first body.
F12 = – F21.
The force of action is equal to the force of reaction.
