Hey,
I'm going into 5th year and plan on crashing Higher Phyics. I've started to teach myself a little and hae grasped it slightly.
My book that I'm using has the Data Shet and the Relationships/Equations needed for the exam and I understand you need to know teh Equations but not the Data Sheet.
Anyway Speed=Distance/Time. I understand this and I also understand what Distance and Time equal and can figure them out comfortably enough.
Although in my book it says you can also right this down as:
V=d/t
or
V=s/t
The book's relationships have Speed=d/t down as: S=vt, which is equalivant to V=s/t and not V=d/t. But what I don't understand is why it's not just written as S=d/t?
In these, what do the letters stand for?
V=d/t
or
V=s/t
Thanks for helping.
PS. In an exam if I rembered it as Speed=Distance/Time and wrote that down, or S=d/t, will I still be given the mark?
