try something like:

force = max(force, 0)

where force is the force applied to the object that you have calculated.

this should ensure that the force is bounded to 0 in the negative
direction.

I believe that in pygame you can use the clock module to help you with your
timing issues (see the docs), and
perhaps attempt to keep a regular frame rate.
