Using Dimensional Analysis (DP IB Physics)
Revision Note
Using Dimensional Analysis
An important skill is to be able to check the homogeneity of physical equations using the SI base units
This is also known as dimensional analysis
The units on either side of the equation should be the same
To check the homogeneity of physical equations:
Check the units on both sides of an equation
Determine if they are equal
If they do not match, the equation will need to be adjusted
