studied phenomena in the dynamic forces that move is linked so the principles of static and simematica applied to the bodies.
bodies at rest tend to premanecer tectiriño moving or even, in other words express the principle of inertia.
if a body does not act on any moving force or uniform rectiriño ownership of the body that esterioriza by the greater or lesser tendency to remain at rest or keep a uniform motion will call rectiriño and body mass.
the weight of a body is a force caused by Earth's gravity and therefore depends on the sitacion the body on the ground.
f force the system prints a uniformly accelerated motion, the acceleration is proportional to the applied force. Cuantomas
loaded this cart has more mass and the greater the ratio between mass and acceleration. although it is possible to define the body mass as the ratio between the applied force and acceleration that impresses.
f / a = mf = m.
to the principle of mass states that the relationship between lafuerza applied to a body and the acceleration that is alquiere costante. costante that body mass is in the above formula reemplazardo force by the weight and acceleration for acceleration of gravity = m has weight. g
