The formula was used to describe a roller coaster in free fall from a stopped position, and the formula was described as V(t) being velocity as a function of time, C as the distance which a body falls in the first second (which was given as 16ft or 5M). I've gotten myself so confused over this...

Homework Statement I have just been watching Caltech: The Mechanical Universe and I'm a little bit puzzled by the instantaneous speed section, i understand the concept, if you try d/t you're deviding by zero at a fixed point so you can instead calculate ahead and reduce down to find the answer...

Thankyou, this has helped me to gain the perspective i was looking for and has provided some new reading material.

I understand that at anything above elementary level we can define something by the properties of the particles that make it up but i mean at elementary level how can we be so sure that two particles which differ only slightly from each other are infact different particles at all rather than the...

I understand this but my question is, why do we class them as completely separate unrelated particles if there is perhaps only a minor difference between the two and should we not consider the fact that a particles properties could differ depending on the environment it is in or some other...

The reason i posted it with an example as oposed to source material is because i no longer had access to the source material, of course one could argue it never existed but then why would i post the question if i knew i had made it up myself. I guess i shall just have to wait until i come across...

I recently read that in the way we class particles if we measure the properties of two different particles and class them as particle A and particle B and continue to measure the properties of a third particle which we find to be only slightly removed from those of particle A that instead of...
