Re: why-o-why



why v=dx/dt instead t=dx/dv?
why dx=(vdt or tdv) instead x=vt?

I'm not sure I understand your question.

Velocity is the rate at which we move, so it's
the change in x over the change in t. Hence
it's delta(x)/delta(t).

As the time is taken over smaller and smaller
amounts, the value of delta(x)/delta(t) usually
gets closer to some value - the limit. So we
write that - and this is simply notation - as
dx/dt. Thus velocity is dx/dt.

Remember, it's not a fraction. It's notation
that represents a limit of a fraction.

So, what was your question?
