The rule in vector notation for the translation to the right is described by the following formula:
Vectorially speaking, a translation is described by the following expression:
(1)
Where:
- Original point.
- Translated point.
- Translation vector.
By direct inspection we see that parallelogram C'D'E'F' translated to the right is moved 9 in +x direction and 4 in -y direction. Hence, the translation vector is equal to:
And the rule in vector notation for the translation to the right is described by the following formula:
V = x/t = 4.5 mil / 3 h = 1.5 mph Since, v = 1.5 mph (or we can say that v is constant), distance and time vary directly and the constant of variation is 1.5 mph.
