In physics, a force is any external effort that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction.. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or a flexible object to deform, or both. Force can also be described by intuitive concepts such as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newtons and represented by the symbol F..A horizontal force pointing NEast can therefore be split into 2 forces, one pointing North, and 1 pointing East... Summing these component forces using vector addition yields the original force. Resolving force vectors into components of a set of basis vectors is often a more mathematically clean way to describe forces than using magnitudes and directions.. This is because, for orthogonal components, the components of the vector sum are uniquely determined by the scalar addition of the components of the individual vectors.. Orthogonal components are independent of each other because forces acting at ninety degrees to each other have no effect on the magnitude or direction of the other.. Choosing a set of orthogonal basis vectors is often done by considering what set of basis vectors will make the mathematics most convenient.. Choosing a basis vector that is in the same direction as one of the forces is desirable, since that force would then have only one non-0 component..0rthogonal force vectors can be 3-dimensional with the 3rd component being at right-angles to the other 2...

Roland (Frankish: Hruodland) (died 14 August 778) was a Frankish military leader under Charlemagnewho became one of the principal figures in the literary cycle known as the Matter of France. Historically, Roland was military governor of the Breton March, with responsibility for defending the frontier of Francia against the Bretons. His only historical attestation is in Einhard's Vita Karoli Magni, which describes him as Hruodlandus Brittannici limitis praefectus ("Roland, prefect of the borders of Brittany") when narrating his death at the Battle of Roncesvalles, when the rearguard, under his command, and the baggage train of a Frankisharmy was beset by rebellious Basques..Herzog Ernst is usually grouped under the heading 'Spielmannsdichtung' or 'Spielmannsepos'. This term is used to describe a handful of other manuscripts of the time, due to the assumption that they were written and told by Spielmänner (a kind of jester).. However, this term has recently been disputed, as these works are considered too complex to have been written by Spielmänner, who are generally thought to have been uneducated..The Song of Roland (French: La Chanson de Roland) is a heroic poem based on the Battle of Roncevaux in 778, during the reign of Charlemagne. It is the oldest surviving major work of French literature. It exists in various manuscript versions which testify to its enormous and enduring popularity in the 12th to 14th centuries. The date of composition is put in the period between 1040 and 1115: an early version beginning around 1040 with additions and alterations made up until about 1115...Scholars estimate that the poem was written, possibly by a poet named Turold, between approximately 1040 and 1115, and most of the alterations were performed by about 1098. Some favor an earlier dating, because it allows one to say that the poem was inspired by the Castilian campaigns of the 1030s, and that the poem went on to be a major influence in the First Crusade. Those who prefer a later dating do so on grounds of what they interpret as brief references made in the poem to events of the First Crusade.... sale is announced of the entire list of Baldwin stock of shares in Andram Consolidated Industries to Mr. Illya Kuryakin..This is not European cropping..
