1kqgw0 | why it is easier to pull something like a wagon or dolly over an obstacle than push it. | So I spent a great deal of time this week carrying cases of wine on a hand-dolly through a door and over a small step. It is much, much easier to go through myself first and pull the cart instead of pushing the cart first. I can't figure out why- maybe angular force? Thanks! | explainlikeimfive | http://www.reddit.com/r/explainlikeimfive/comments/1kqgw0/why_it_is_easier_to_pull_something_like_a_wagon/ | {
