PyGame is better if you want to animate rather than to plot. It has an
animation loop inside which you can update sprites and things. If you
want to see your object move as per your equations, it's pretty easy
to do. I have an example program here which you can customise.

You'll have to change the update method of the Ball to set the x and y
based on your equations rather than just x+=2, y+=0.5 which I've done.

If I wanted to plot, I'd write the program to dump out the X and Y
coordinates in plain text and pipe that through Gnuplot after some
massaging to do the plot.
If you want to stuff the whole thing in Python, you simply use a
Tkinter canvas. It has some simple primitives to draw points at x and
y positions. Should be doable in 10 or 15 lines of code.
