>Why isn’t a penny dropped from space able to kill you?
Because earth has an atmosphere and the constant friction caused by an object’s drag during the fall means that there is a hard limit on how much it can be accelerated. At some point it will reach its terminal velocity and that’s it. A penny dropped from 100km will have the same velocity (and therefore the same kinetic energy) on impact as a penny dropped from 1km.
