Answer to Question #29160 in Mechanics | Relativity for Samama Fahim

Question

What I'm going to ask is very confusing for me. In my Calculus book, I read;

s(t) = distance a particle travels from time '0' to 't'.
v(t) = velocity of a particle at time 't'.
a(t) = acceleration of a particle at time 't'.

My first question is; Are velocity, distance, and acceleration only the function of time?
If they are not, then in which case they are only the functions of time? Because, in the above three functions, they seem to be the function of time only.
