Forces
Contact forces
Friction
The force of friction is what causes the speed of an object to decrease little by little because of the friction it has against the ground.
Normal
The normal force is the force exerted by a surface against an object to prevent it from sinking into it, its direction is perpendicular to the surface.
Pressure
The effect that the contact forces have is that they generate a pressure on the surface on which they are acting, for example if you apply 500n of force in an area of 2cm² we will have to divide the force between the area and it will give us a pressure, which in this case is 250 and has two types of metric units, one would be n/cm² and the one used is pascals (Pa). The equivalences between these are very simple since 1 n/cm² = 1 Pa
Exereted with our body
The main forces exerted on a body are: our weight, the normal force and the friction force.
Tension
It is known as tension force to the force that, applied to an elastic body, tends to produce a tension; This last concept has various definitions, which depend on the branch of knowledge from which it is analyzed. Strings, for example, allow forces to be transmitted from one body to another.
Non-Contact forces
Magnetic
The magnetic force is generated by the movement of the electric charges that are inside the atoms of an object, that is to say that if two charged objects with the same direction of movement have a force of magnetic attraction between them.
Electric
The electric force is what implies that two objects with a magnetization attract or repel each other, if the magnetizations are equal the poles will repel each other, but if one is - and the other is + they will attract each other
Gravity
Gravity is a force that attracts objects towards its core, for example the earth, being a body with a large mass, has its own gravity and the core of the earth is the center/core of its gravity and anyone who enters its atmosphere will be pulled toward the ground by the force of gravity
Newton Law forces
2Nd law: Law of forces
Newton's second law establishes the relationship between a force applied to an object, the mass of that object and the acceleration that object obtains when pushed by that force, for example if a 50 kg body receives a force of 800 n it will have an acceleration that will be the result of the division between F/M= A and gives us a result of 16 m/s2 which gives us that it would have an acceleration of 16 m/s2

1St Law: Law of inertia
Newton's first law is the law of inertia and says: "Every body preserves its state of rest or uniform and rectilinear motion unless it is forced to change its state by forces impressed on it" by this it means that if a body is with a constant speed or stationary means that no force is being applied on it.
