basic quantities

From what i had learned from this chapter were the meaning of physical quantities, base quantities and derived quantities. As well as prefix, scalar quantities and vector quantities. First of all is about the meaning of physical quantities which refer to as a quantity that can be measured by using instrument.

While base quantities is a quantity that cannot derived from any other physical quantities. Derived quantities is a quantity obtain from combination of base quantities. Scalar quantity is a quantity that have a magnitude while vector quantity is a quantity that have both magnitude and direction.

 There's a time when i'm stuck at vector. As in i'm not quite sure if i'm doing it with the right way. And during the first exam, i notice that repeatedly making mistake while doing the Homogenity equation although i know how to solve it, i still got stuck. In conclusion, I'm sure by doing lots of exercise regarding this topics i can get the point.
