IIRC the force of gravity is negative if up is in the positive direction.

The time before time 0 in an experiment is negative time.

Potential energy can be negative.

Try it. Remember, you will have to cover the same material. Every example and exercise will have to be converted your non-negative system. It will probably drive you crazy, especially when you realize how much work you save, and how much easier it is to gain important insights if you are able to use negative numbers in physics.
