Huh? How does that work? Certainly doesn't generalize to all vehicles.

- dylan604 3y agoWhen breaking down the vectors of a pushing force, one of them is always applying pressure into the ground while the vectors of pulling are always away from the ground.
- EnigmaFlare 3y agoI see. But how does that make either way more expensive? Those forces require no work to apply because there's no motion into or out of the ground. Furthermore, they're counteracted by opposite forces on the bicycle itself - while the bicycle is pushing the front trailer downwards, the front trailer is also pushing the bicycle upwards. So even if you consider greater downforce to be a problem (eg. more rolling resistance), it's not greater for the overall system.
