basic high school / Newtonian physics of everyday objects. (E.g., "If I drop this penny off this building, how long will it take to hit the ground?"

This is tricky: basic high school physics lies to you all the time. Example: it says that a penny and a large paper airplane weighting the same as the penny will hit the ground at the same time.

In general, getting the right answers from physics involves knowing the assumptions of of models used and at which points they break down. Physics will tell you, but not at the high school level and you have to remember to ask.
