Kinetics: part of Physics that Studies the movements without pay attention to the causes that produce these movements.
Dynamics: part of Physics that studies the movements which paying attention to the causes that produce this movements
Forces: causes that produce movements.
Trigonometry: part of Math that relates the angles and distances.
Newton’s first law: If there isn’t resultant force acting on an object. If it’s at rest, its will stay at rest and it’s moving, it keeps on moving at constant velocity in a straight line. Inertia: is the reluctance to change velocity, inertia depends on mass.
Newton’s second law: If we apply a force in an object, its velocity changes. The change in velocity is called acceleration, and this is directly proportional to the RF on the object. If the acceleration is 0, RF is 0. Weight: force with earth attracts an object.
Newton’s third law: If A exerts a force on a B exerts equal but opposite force on B.

Fluid: substance whose states are liquid or gas, this don’t have a constant apply shape. In fluids the particles are moving constantly.

Pressure: is the relation between the force applied and the surface we are going to apply.
The uptrust depends on the density and on the volume.
Arquímedes ´ Law: todo cuerpo sumergido total o parcialmente en un líquido experimenta un empuje vertical hacia arriba de igual valor que el peso del volumen del fluido desalojado.
