Question

If you are pushing a box up a ramp, would a gravel ramp or a wooden ramp be more efficient, and why?

Answer 1

A wooden ramp would be more efficient for pushing a box up a ramp compared to a gravel ramp. This is because the wooden surface provides a smoother and more stable surface for the box to slide up on. In contrast, the uneven and loose surface of the gravel ramp would make it more difficult to push the box up as it may cause the box to slip or get stuck. Additionally, the friction between the box and the wooden ramp would be less compared to the gravel ramp, making it easier to move the box up the ramp.
