Oh my, the level to which nitpickers will go… my point is that the “false” statement from OC is in fact true for most people in their daily life. Try to ride a bike to understand what they experience.

It’s not even necessary to qualify that statement, unless you are discussing situations on earth vs situations in space. That’s why OC is false imo, because he takes a common understanding out of its context.

The statement is false in space travel and planet mechanics, which most people don’t do daily, and don’t need to consider, or if you look at it from the point of the physics book, which in this case conveniently ignores the situation most people are in most of their lifes: on earth where friction and air resistance are a reality.

My whole point is this context shift is willful misunderstanding.
