WebSep 11, 2024 · The dot product is known as a scalar product and is invariant (independent of coordinate system). An example of a dot product in physics is mechanical work which is the dot product of force and distance: (14.5.7) W = F → ⋅ d →. The cross product is the product of two vectors and produce a vector. WebIn fact, it may appear scalar, depending how you define differential cross-section vector d A → in definition of current I = ∫ J → d A →. If you define it so that it changes direction under parity inversion, then I is pseudoscalar. Otherwise, it's scalar. Or I may be wrong, and d A → has some unambiguous definition. colchon hera spring

WebScalar quantities have only a magnitude and do not depend upon any direction. Vector quantities have both the magnitude and the direction. Power The rate at which work is done on an object is defined as power. P o w e r = w o r k ( e n e r g y) t i m e WebDrag curve. The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed.
