Meet the Newton's Laws: ISaac Newton was an important name that helped to write how the dynamics of moving bodies works.
The apple falling on his head was the beginning of a journey of great discoveries.
Scientist Isaac Newton made the study of gravity and then studies force and closing with the creation of the three Newton's laws.
In kinematics, the movement of the body is studied without understanding its house. In dynamics, the relationship between movement and force is studied.

Basically it's the interaction between two bodies. The effects that are noted in the cause of force are:
The resulting force on a body will be equal to the vector sum of all the forces that are applied. Newton's three laws are called Classical Mechanics or Newtonian Mechanics and are considered fundamental pillars.
When we are inside a car and a turn is rounded, our body remains at the same vector velocity it was submitted to before the car made the turn.
The impression you have is that the body is being thrown to the opposite side of the curve. This is because the velocity is tangent to the trajectory.
When we are in a car and it suddenly brakes, we feel that we are being thrown forward and our body tends to keep moving.
A body at rest has a tendency to remain at rest and a body in motion remains in motion.
A body will only change its state of inertia if someone or something applies a net force.
When a force is applied to two bodies of different masses, this force does not produce equal acceleration. This 2nd Law of Newton shows that shape is always proportional to the product of the acceleration of a body and its mass.
F = ma
F = is the force resulting from all forces acting on the body (in N)
M = is the mass of the body at which the forces act (in kg)
a = is the acquired acceleration (in m/s (2) square)
The unit of force in the international system is N (Newton) which is equivalent to kg m/s (2) squared (kilogram meter per second squared).
When a force of 12 N is applied to a 2 kg body, what acceleration will be gained?
F = ma
12 = 2ª
A = 6m/s (2) square
Traction force: is a system where a body is pulled by a string that is inextensible, flexible and has negligible mass. The force is applied to the wire which applies a force to the body called the Tensile Force.
When a box is pushed with a force F, this force is called an action.
Newton's 3rd Law shows that whenever this occurs, there is another force with equal magnitude and direction and the opposite direction of the force, called Reaction Force.

Forces always happen in pairs, for all action forces there is a reaction force.
