Physics Lab- please help?

So, I am doing a lab for physics about work and energy. We calculated the work and force of a car going up and down a 30 degree and 45 degree ramp. I filled in a chart that had suspended mass, distance, work and friction, and car mass. For the questions at the end of the lab it says " Suppose the car accelerated up and down the incline. How would this affect the experimental determinations?"

    It is not clear what they are asking. But maybe they want something like this:

    mass is unchanged.

    distance (displacement) is negated (e.g. 30cm becomes -30cm)

    work by mass done is negated

    friction is unchanged
