Reading Assignment 2 on Space, units, scalers, vectors, tensors and other stuff:
Readings on Position, Velocity, Acceleration and Rates of Change (You don't need to read everything; just browse a bit. This will be a good reference if you need help on problems.)
The SI system of units (Look at the introduction.)
Everything you ever wanted to know about vectors (This is more for reference and possible help on homework problems. Please don't go beyond the basic stuff, unless you want to know more and have time.)
A brief introduction to tensors (Somewhat hard to understand, but read the first page to get an idea of what a tensor is.)
