Vector quantity - Study guides, Class notes & Summaries

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 When are the four forces that act o...

DIstance : · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement : · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position : · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direction matters. But distance is a ...
