1) What are the sources of random and systematic error in this experiment and how can you improve your results? 2) Is it possible to find the initial velocity using Newton's second law instead of the Conservation of Energy? Explain using formulae and equations. 3) What are the advantages of using Conservation of Energy method to determine the initial projectile velocity?

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
