Dimensional Analysis Flashcards
1
Q
Recall common derived SI units (e.g N, J, W) and express them in terms of base units
A
- Newtons is a force which is mass x acceleration - therefore it is kg.ms-²
- Joules is derived from work done - force x distance - therefore it is kg.m²s-²
- Weight is derived from mass x gravitational field strength - therefore it is kg.ms-²
