Si Units Info (binary/octet-stream)

Delightful Definitions!!!

Scalar: have magnitude only e.g. 100kg

Vector: have both magnitude and a direction e.g. 100N at 40 degrees from North

Combining vectors

Vectors can be combined by placing the start of one at the end of the other. The final vector is calculated using Pythagoras/Trigonometry Trigonometry is SOHCAHTOA
