The principle of maintaining the impulse given by claiming that the total momentum of all bodies in the universe (or impulse of an isolated system) does not change (a constant). One consequence of this is that the center of mass of any system of the body still continues to move at the same speed as an external force does not act on it.
Maintaining the pulse is a consequence of the homogeneity how to stop a toothache of space, or the fact that in space there are no salient points, but they all point in the space of equivalent or equal. how to stop a toothache It also applies the other way around. That is, if a body at a point of space changed their speed (your pulse) without the influence of external forces, it would have concluded how to stop a toothache that this point is a little different from other points how to stop a toothache of space, or less said, the featured item, which would mean that this space is not homogeneous. how to stop a toothache
In an isolated system (in which no external forces acting) the total momentum is constant, which is in accordance with Newton's law inercije.Treci Newtonian law (the law of action and reaction), which argues that the forces of interaction of two bodies how to stop a toothache of the same strength and direction, and opposite direction, it is also in conformity with the law of maintaining impulse.
For example, when a bullet from a gun, it appears that the total momentum of the system increased compared to the previous state. However, pulse bullet in one direction is equal in intensity, but of opposite sign, the pulse rifle which moves in the opposite direction. By adding pulses and pulse rifle shots so we get zero, which is also equal zero pulse which is a system-rifle bullet how to stop a toothache possessed before the shots began to move.
Angular velocity is a vector that describes the physical size of the speed and direction of rotation of a body. Its intensity is numerically equal to the corner how to stop a toothache (Θ) (expressed in radians) that the body in the course of their rotation describe the unit of time (t). Accordingly, a unit of angular velocity in the SI system is the radian per second. The direction of the angular velocity coincides with the direction of the axis around which the body rotates, how to stop a toothache the direction is determined by the rule "clockwise" (or rule right screw). Under this rule, the observed rotation how to stop a toothache of the body from the top of the angular velocity vector is opposite how to stop a toothache the direction of movement of the hands on a clock (or if the right screw parallel to the axis of rotation reversed in the direction of rotation of the body, the direction how to stop a toothache of his "progression" (or "decline") is equal to the angular direction of the vector speed, for example, if the cap on the bottle reversed in the same direction as the body rotates on the "progress" toward the bottle or "regress" of the bottle, which will be in both cases the same direction of the angular velocity how to stop a toothache of the body, as well as the cap, of course). The angular velocity is related to the speed of revolution of the heavenly bodies, which is measured in units such as the revolution how to stop a toothache in one minute. Indication of angular velocity is the Greek letter omega (ω). Angular velocity of astronomical objects usually means a capital letter omega Ω.
This physical size was found in a rotary motion. It is not only essential intensity of the forces acting on the body, but also where the body is offensive point of force, or as a distance how to stop a toothache attack how to stop a toothache point force from the axis of rotation
