G10 3Q Science: All the terms in Scalars & Vectors

Scalar

-quantity that has only magnitude and no direction.

Vector

-has both magnitude and direction.

- both are associated with units

- both are used in mathematical operations

- both represent physical quantities

Similarities of Vectors and Scalars

tail

the origin of a vector

head

the end point of a vector

Vector arrow

vectors are commonly represented

in diagrams by an arrow called as

magnitude

length of the vector arrow

direction

the head of the vector arrow

Scale

the ratio of the distance

Head-to-tail method

- Placing the tails of the second vector at the head of the first vector. The third vector is placed at the head of the second vector.

- you can see how vectors combine

- by doing this, you can visualize both the magnitude and direction

- you can understand the relationship between different vectors.

- provides a fast way to get a rough idea of the resultant vector

Resultant vector

- vector sum of two or more vectors

-it's the vector that describes the total effect of several individual vectors when combined.

Analytical method

this method is used to add 3 or more right angle vectors

Component method

- this method is used to add non-perpendicular vectors

- a technique used to break down a vector into its individual components along specific axes of a coordinate system
