Fundamental Principles of Force, Motion, and Gravity

A physical deformity, affecting its strength or motion or any reason is subject to change pausagune situations. Vector magnitude of forces and Newton (N) are measured in international system. Point of application, indicating the strength of what reagiten points, and the force vector that represents the starting point. Is the numerical value of the power module. Coincides with the vector length. Meaning what direction the force is applied. A two-way direction of forces in the same direction may be, contrary to each other. Vector is indicated by the arrow on the end. Exploring the dynamic forces of physics responsible for the mechanical part is formed with the kinematics. Of contact forces, contact with body, must be shown to, diztantzia forces, the interaction between the two bodies separated by a certain disatantzia happens. Erresultantea + forces that affect the body all the forces that would have been influenced by the strength of the effect is the same. + Extension or compression of a spring is proportional to the springs in indarrarekiko.F = Kx + dinanometroa used to measure the strength of the value of a da.Funtsean Dec device, a calibrated spring. 1.Inertziaren principle: that the forces acting on a body when erresultantea zero (0N = R), the body takes a constant speed (HZU). Pausagunean already there, and the speed remains constant pausagunean had du.Izan continue at the same rate as the movement of the body Resistance to change in the set (inertia). Handidun More bodies dute.Indar inertia greater balance is to be null and as a result of the sum of all forces, the body can still say higitzea.Alderantzizkoa constant speed or, in other words, if a body or its speed pausagunean is constant, then the balance of power is. 2.Dinamikaren basic principle: that the forces acting on a body when it is not null erresultantea (R 0N iuela not), the body force and acceleration in the direction of acceleration will be proportional to this force, but the mass will be proportional to the reverse-reaction 3.Akzio da.F = ma principle: a body affects other bodies to a force (action), the latter also affects the strength of the first in the same direction, but the opposite direction (reaction). Action-reaction principle that the two forces met: normal weight and strength. + weight: the body to attract the Earth The strength of the Earth, for zentrorantz vector magnitude is measured in Newton and da.P m.G + = normal force (N): Surface deformation prevents the force is always perpendicular to the surface and is measured in Newton. + + of the universal law of gravity (Newton ): the force of attraction between two bodies is directly prportzionala biderkadurarekiko mass of bodies and two bodies is proportional to the distance karratuarekiko vice versa, izanik.G Gravitational constant G = 6,67.10-11 re N.Mkarratu / kg square.
