V = u + a t , s = ( u + v 2 ) t , v 2 = u 2 + 2 a s , s = u t + 1 2 a t 2 , s = v t ? 1 2 a t 2 . The quantities s , u , v and a are all vector quantities so therefore their sign represents the direction of motion.

Basic Steps to Setting Up Equations Determine what the question is asking. Write down the relevant information in simple statements. Assign symbols to unknown values that need to be found. Determine how the statements relate to each other mathematically.

The Trick to Dimensional Analysis is to keep your units in your conversion factors, and set them up so all units cancel except the units you want in your answer. This is easiest seen by looking at a problem.

Performing dimensional analysis is a pretty easy process. All you have to do is set up a series of fractions where the units end up canceling out. Remember, when you have fractions and want something to cancel out, you have to make sure it is present in both the numerator and denominator.

There are innumerable physical quantities for dimensional analysis. One learns about all these quantities gradually with every new chapter of the course. There is no need to learn everything initially in the dimensional analysis chapter. Still, in case, there is a need of a list of quantities, the link is mentioned.
