Your attempt at this is correct. when an object falls, some of the gravitational energy is converted to other forms such as kinetic energy. the amount lost is the amount of work done by gravity.

Hey BvU thanks for the reply, What kind of experiment would you recommend? the size of the tire and load (0.5tone tire and 10 tonne load). I was thinking measuring the hysteresis and thus getting the loss due to rolling, but i couldn't think of a safe was of doing it. thanks

I am comparing three brands of tires to see which one provides the lowest rolling resistance and thus give the best efficiency at low speeds. I have the information of the tires such as footprint, weight (of the tire and load), speed. How would i go about doing this ? am really stumped thanks
