Vector quantity - Study guides, Class notes & Summaries

NIFE Aero Latest Version with Certified Solutions Define Vector A quantity that expresses both magnitude and direction. A vector quantity is represented by an arrow that displays direction and has a length proportional to magnitude Moment Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") Equilibrium Flight When the sum of all FORCE and all MOMENTS around the COG are equal to zero ...

Honors Physics - Final Exam Review with Complete Solutions What is the principle of superposition in wave interference? The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves' amplitudes. How does the frequency of a wave relate to its wavelength? The frequency of a wave is inversely related to its wavelength; as the frequency increases, the wavelength decreases, and vice versa. What is the role of an ele...
