Scalar and Vector Measurements
This is a simple physics tutorial aimed at high school students in grades 9 and 10 (GCSE, HSC) answering the common questions:
- What are scalar measurements?
- What are vector measurements?
- How do vector and scalar measurements differ or compare?
Importantly you may find this written maths tutorial a useful introduction to scalar and vector measurements for physics.
What are scalar and vector measurements?
As the question suggests, both scalars and vectors are a form of measurement. Where they differ is that scalar measurements only describe magnitude (or size), whereas vector measurements describe both magnitude and direction.
The video above goes through three examples of scalar measurements: volume, temperature and distance. It also describes how distance can be changed to become a vector measurement - there's also more about that here.
