Vectors

Vector quantity

Kuantiti yang mempunyai kedua-dua magnitud dan arah

Scalar quantity

A quantity that has magnitude but no direction

A vector is usually represented by a directed line segment drawn as an arrow

The length of the line represents the magnitude or the size of the vector and the arrow indicates the direction of the vector

Two vectors are equal if and only if both the vectors have the same magnitude and direction

A zero vector has magnitude zero and its direction cannot be determined

Resultant vector

Combination of two or more single vectors

Two vectors are the same if both vectors consist of same magnitude and direction

A vector is negative if the vector consists of the same magnitude but is moving in the opposite direction

Method for obtaining resultant vectors for non-parallel vectors

-Triangle law -Parallelogram law -Polygon law

Triangle Law

Parallelogram Law

resultant vector is the diagonal of parallelogram

Polygon Law
