This applet hope to help you understand relation betwen x(t), v(t) and a(t).

\$v(t)=limit_{Delta tightarrow 0}frac{Delta x}{Delta t}= frac{dx(t)}{dt}\$ , and \$a(t)=frac{d v(t)}{dt}\$

The applet will draw x(t),v(t) and a(t) when you drag the tiger horizontally =>to change it's position.
You can also set up acceleration or velocity with slider and click accelerate to star the acceleration.
The step is for you to move one time step at a time.
