Problem:
Source: Halliday et al Physics 4e, p9, sample problem 4.
Why is it valid to assume that $$F\alpha v^b$$ as the author does here, and not some more complex equation e.g. $$F=av^{e_1}+bm^{e_2}+cr^{e_3}$$, or $$F=av^{e_1}+bv^{e_2}+\cdots $$ (or some other equation)?
A very similar question I had is from same source, page 10, sample problem 5:
Again, why can authors assume that the variables appear as a product without there being any summing involved?
