1.3 – Vectors and scalars
Description
Nature of science:
Models: First mentioned explicitly in a scientific paper in 1846, scalars and vectors reflected the work of scientists and mathematicians across the globe for over 300 years on representing measurements in three-dimensional space. (1.10)
Understandings:
- Vector and scalar quantities
- Combination and resolution of vectors
Applications and skills:
- Solving vector problems graphically and algebraically
Guidance:
- Resolution of vectors will be limited to two perpendicular directions
- Problems will be limited to addition and subtraction of vectors and the multiplication and division of vectors by scalars
Data booklet reference:
International-mindedness:
- Vector notation forms the basis of mapping across the globe
Theory of knowledge:
- What is the nature of certainty and proof in mathematics?
Utilization:
- Navigation and surveying (see Geography SL/HL syllabus: Geographic skills)
- Force and field strength (see Physics sub-topics 2.2, 5.1, 6.1 and 10.1)
- Vectors (see Mathematics HL sub-topic 4.1; Mathematics SL sub-topic 4.1)
Aims:
- Aim 2 and 3: this is a fundamental aspect of scientific language that allows for spatial representation and manipulation of abstract concepts.
